A piece of metal displaces 5 ml of water and has a density of 10.78 g cm3 what is the mass of the metal?

1ml volume = 1 cm^3 volume
so take 10.78 g/cm^3 multiply by 5 cm^3 and the cm^3 cancel out leaving you the mass.
10.78 g/cm^3 x 5ml = 53.9 g

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.)
How much does metal weigh under water?
Metal weighs less under water than out of it. This is because water is much more dense than air, and anything put in water will feel the effects of the water. The affect appears as what is called buoyancy, which is a force. When we think of metals, we generally think of them as being at least a little bit heavy. Most times that we put a piece of metal in water, it sinks, so let's look at this as the nature of the question. When a piece of metal sinks, it displaces a volume of water equal to its own volume. The metal, which had a certain weight in air, will now weigh less. Its weight in water will equal its weight in air less the weight of the volume of water that it displaced when sinking. Different metals have different densities, and will (of course) have different weights for a comparable volume other metals. [This is a general answer. It ignores trying to sink metal into solid water, and it also overlooks the chemistry of some metals. Some metals, like those in groups 1 and 2 of the periodic table, will react with water. No tricks here; nothing up the sleeves.]
How to find out the density of a piece of magnetite?
First you weigh it, then you put it in a beaker with a known amount ow water in it. By noting how much the volume of water increases you get the volume of the magnetite. Now you got all you need to determine the 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.
What is the volume of a rock that displaces 1500mL of water?
1,500 mL
A 6 kg piece of metal displaces 1 liter of water when submerged what is its density?
If the water is at standard temperature and pressure (25 degrees Celsius and one atmosphere), the water has density of 1 kilogram per liter. When submerged, the metal displaces its own volume of water. Therefore, the volume of the metal is 1 liter, and the density of the metal is 6 kg/liter.
Why does a piece of wood float when a piece of lead sinks and they both have the same volume?
The density of the wood is lower than the density of the water, so the water displaces the wood and is held to the 'floor' by gravity. Lead is more dense, so it can displace the water and sink.
Why does a steel ship float even though a piece of steel dropped in the water sinks?
A steel ship floats because it is designed to displace enough water to generate a buoyant force greater than its weight. When a piece of steel is dropped into the water, it sinks because its density is greater than that of the water, causing it to displace less water than its weight, leading to sinking.
Why does a ship built from heavy metal float on water while metal actually sink in water?
An object will sink in water if it has a greater density than the water. This refers to the object's TOTAL or AVERAGE density, not necessarily the density of individual parts. Specifically, in the case of a ship, it includes the air that is trapped inside.
Why is wood is more buoyant than metal?
Wood is more buoyant than metal because wood has a lower density than metal. Buoyancy is a result of the object's density compared to the density of the fluid it is in. Since wood is less dense than metal, it displaces more water and experiences an upward buoyant force that keeps it afloat.
The density of titanium metal is 4.51g per cm cubed at 25 C what mass of titanium displaces 65.8 mL of water at 25 C?
First, convert the volume of water to grams using the density of water. The density of water is 1g/cm^3, so 65.8 mL of water is equivalent to 65.8 grams. Since the mass of the titanium displaces an equal volume of water (65.8g), the mass of the titanium is also 65.8g.
What is the density of a piece of titanium that has a mass of 72 grams and displaces 16 milliliters of water?
The density of the titanium can be calculated using the formula: Density = mass/volume. Plugging in the values, Density = 72g / 16mL = 4.5 g/mL. Therefore, the density of the titanium is 4.5 g/mL.
How will you determine if something will float in water?
You can determine if something will float in water by comparing its density to the density of water. If the object is less dense than water, it will float. If it is more dense, it will sink. You can also use the buoyancy principle: an object will float if the weight of the water it displaces is equal to or greater than its own weight.
What is the density of a 12.5-gram object that displaces 16 cubed centimeters of water?
The density is 0,78 g/cm3.
What is the density of a 9.0 gram object that displaces 13 cm3 of water?
The density of the object can be calculated using the formula: Density = Mass/Volume. In this case, the mass of the object is 9.0 grams and it displaces 13 cm3 of water. Thus, the density of the object is 9.0g / 13 cm3 = 0.69 g/cm3.
Which of these objects will most likely float?
Any with a density less than water, or, like a metal ship, an object with a shape which makes its volume greater than the volume of water that it displaces and is sealed so that water will not flow into it.
What would be the density of a 10 gram object that displaces two milliliters of water?
To find the density, divide the mass of the object by the volume of water it displaces. In this case, the density of the object would be 5 grams per milliliter (10 grams / 2 milliliters).
