A nugget of gold with a mass of 521 g is added to 50.0 mL of water. The water level rises to a volume of 77.0 mL. What is the density of the gold?
To find the density of the gold, we first determine the volume of the gold nugget by subtracting the initial water volume from the final volume: 77.0 mL - 50.0 mL = 27.0 mL. Density is calculated using the formula ( \text{density} = \frac{\text{mass}}{\text{volume}} ). Thus, the density of the gold nugget is ( \frac{521 , \text{g}}{27.0 , \text{mL}} \approx 19.3 , \text{g/mL} ).

A nugget of gold with a mass of 521 g is added to 50.0 mL of water The water level rises to a volume of 77.0 mL What is the density of the gold?
Assuming the gold nugget is solid and pure (unlikely in real life!) The volume of the nugget is 77.0 - 50.0 mL = 27.0 mL So density = mass/volume = 521/27.0 = 19.3 g per mL.
How can you figure out the density of a irregular rock?
To determine the density of an irregular rock, you can use the water displacement method. First, measure the initial volume of water in a graduated cylinder. Then, submerge the rock completely in the water and measure the new water level; the difference in volume indicates the rock's volume. Finally, divide the mass of the rock (measured using a scale) by the volume obtained from the water displacement to calculate the density.
What is the difference between volume and density?
Simply: Volume (V) is how much space an object takes up whereas density is how "compressed" an objects mass (m) is. Density = m/V Example: Imagine a ton of feathers and a ton of iron. They both have the same mass (weight) but they have different volumes and density.
A piece of metal with a mass of 167 g is placed in a 50 mL graduated cylinder The water level rises from 20 mL to 36 mL What is the density of the metal?
Density = mass/volume = 167g/ (volume displaced) = 167g / (36mL - 20mL) = 167g/16mL = 10.4g/mL. Density is usually recorded in g/cm3 which is the same as g/mL so the density is 10.4g/cc. Also, to be extra correct, the answer should be rounded to 10g/cc because 16mL only has 2 significant figures so that is the number you report in your final answer.
A piece of metal with a mass of 163 g is placed in a 50 mL graduated cylinder The water level rises from 20 mL to 36 mL What is the density of the metal?
The volume of the piece of metal is measured by the difference in the volume of water in the graduated cylinder before and after the piece of metal is placed in the cylinder. This is stated to be 36 - 20 = 16 mL. Density is defined to be mass per unit volume. Therefore, for this piece of metal the density is 163/16 = 10 g/mL. (Only two significant digits are justified, because the is the number of significant digits in the limiting datum 16.)
A nugget of gold with a mass of 521 g is added to 50.0 mL of water The water level rises to a volume of 77.0 mL What is the density of the gold?
Assuming the gold nugget is solid and pure (unlikely in real life!) The volume of the nugget is 77.0 - 50.0 mL = 27.0 mL So density = mass/volume = 521/27.0 = 19.3 g per mL.
A nugget of gold is placed in a graduated cylinder that contains 85 mL of water The water level rises to 225 mL after the nugget is added to the cylinder What is the volume of the gold nugget?
The volume of the gold nugget can be calculated by finding the difference in volume before and after adding the nugget. The volume of the gold nugget is 225 mL (final volume) - 85 mL (initial volume) = 140 mL.
A nugget of gold is placed in a graduated cylinder that contains 80 ml of water the water level rises to 225 ml after the nugget is added to the cylinder what is the volume of the gold nugget?
The volume of the gold nugget can be calculated by subtracting the final volume (225 ml) from the initial volume (80 ml) of water in the graduated cylinder. Therefore, the volume of the gold nugget is 145 ml.
A nugget of gold is placed in a graduated cylinder that contains 80 mL of water the water level rises to 255 L after the nugget is added to the cylinder what is the volume of the gold nugget?
Agreed with your correspondent(AnswerBot)!!! However, it must be a huge measuring cylinder if it has a volume of 255 L . I think you mean 255 mL. 255 L is 255 litres = 255,000 mL , which is a quarter of a cubic metre. Please ensure that you correctly insert the units.
Is a Nugget real gold or fools gold if a it has a mass of 100.0 g and displaces the water level in a graduated cylinder by 15.0cm3 from 10.0cm3?
density=g/cm3 The density of Gold is 19.3g/cm3 The density of Fool's Gold (pyrite) is 5g/cm3 The question is slightly ambiguous as first written so two calculations are given: # 100/15= 6.666g/cm3 So this nugget is possibly pyrite and not gold. 100/5= 20g/cm3 So this nugget is possibly gold.
How do you calculate the density of air?
To calculate the density of air, you divide the mass of air by its volume. The formula is density mass/volume. The density of air is typically around 1.225 kg/m3 at sea level and 20 degrees Celsius.
What is the density of an object with a mass of 2g that when placed in a graduated cylinder with water raises the volume of water from 20ml to 30 ml?
The volume of the object is the difference in water level before and after the object is added, which is 10 ml (30 ml - 20 ml). The density of the object is mass divided by volume, so 2g / 10 ml = 0.2 g/ml. Therefore, the density of the object is 0.2 g/ml.
What is the weight of a 10kg mass at sea level?
That would depend on the volume (density) of the 10kg object.
How could you find the density of a potato?
first, you weigh it to get its mass. then you acquire its volume, since it has an irregular shape, you apply water displacement method. get a calibrated cylinder, note the initial water level and gently drop the potato in. measure the resulting water level and subtract it with the initial water level. this is your volume. density= mass/volume simply divide what you measured in grams with the volume of the potato (cm3). unit of density is grams per cubic centimeter or g/cm3
28.5 grams of iron shot is added to a graduated cylinder containing 45.50 milliliters of water The water level rises to the 49.10 milliliter mark From this information calculate the density of iron?
mass = 28.5 g volume = 49.10 ml - 45.50 ml = 3.60 ml density = mass / volume = 28.5 g / 3.60 ml ~= 7.92 g/ml 1 ml = 1 cu cm Therefore density of iron is approx 7.92 g/cm³
How do you get dentisty when you have measure volume and mass?
Density = (mass) divided by (volume). You must have known that at some level; otherwise, how did you decide that mass and volume were the things to measure, instead of, say, weight and temperature ?
Why do water level decrease when you pour salt in the water?
The volume of the solution will NOT be the same after salt is dissolved. In fact, in a saturated solution of NaCl, the volume actually goes DOWN slightly. The explanation is too complex for this discussion. Some salts will increase the volume. You may not notice the change, and it will depend on the amount of salt added. The more salt, the greater will be the change in volume.
