The density for a sample of a pure material with a volume of 5 cm3 and a mass of 20 grams is?
The idea is to divide the mass by the volume.
What is the density of a 600 gram metal with a volume of 30 ml?
Density = Mass/Volume = 600/30 = 20 grams per ml.
How many milliliters in 20grams?
Milliliters is volume and grams is mass, so you need to know mass density to solve this. For water, it has mass density of 1 gram per cubic centimeter which is the same as 1 gram per millitre of volume. So for water only, 20 ml = 20 grams.
If a 2 inch cube is 20 grams how heavy is an 8 inch cube of the same material How is this Calculated?
The volume of the little cube is 23 = 8 cubic inches so the density of the material is 8/20 = 0.4 grams per cubic inch.The volume of the large cube is 83 = 512 cubic inches, so the mass (not the weight) is 512*0.4 = 128 grams.
What is 20 percent of 2000 grams?
20% of 2000 grams= 20% * 2000= 0.2 * 2000= 400 grams
If 5 ml of ethanol has a mass of 3.9 grams and 5.0 ml of benzene has a mass of 44 grams which liquid is more dense?
Benzene is more dense than ethanol. This can be determined by calculating the density of each liquid using the formula density = mass/volume. In this case, benzene's density is higher than ethanol's because for the same volume, benzene has a higher mass.
What is the volume of 300 g benzene if it has a density of 0.88 grams per mL?
The volume of 300 g of benzene can be calculated by dividing the mass by the density. In this case, 300 g / 0.88 g/mL = 341.35 mL. Therefore, the volume of 300 g of benzene is 341.35 mL.
What is the density of an object with a volume of 10ml and a mass of 20 grams?
Density = Mass / Volume So, density of an object with a volume of 10ml and a mass of 20 grams is = m / v = 20grams/10ml = 2g/ml
What is denser 20 grams or 25 grams?
25 grams is denser than 20 grams because density is a measure of how much mass is contained in a given volume. Since both masses occupy the same volume, the one with more mass (25 grams) will have a higher density.
The density of benzene at 15 is 0.8787 Calculate the mass of 0.1900 of benzene at this temperature?
To calculate the mass of benzene, use the formula: mass = volume x density. You need to know the volume of 0.1900 L of benzene at 15°C, which can be calculated using the ideal gas law or the formula for density (density = mass/volume). Once you have the volume, multiply it by the density to find the mass.
What is the density of a substance with a mass of 20 grams and a volume of 5 cubic centimeters?
It is: 20/5 = 4 grams per cm3
What is the density of an object that has a mass of 100 grams and a volume of 5 grams?
Density is calculated by dividing the mass of an object by its volume. In this case, the density would be 100 grams / 5 grams = 20 grams per cubic gram.
How many grams are there in one moleof benzene?
Benzene has a chemical formula of C6H6 This has a molar mass of 78. So one mole has a mass of 78 grams
How do you convert weight volume to volume volume?
to calculate the weight from the volume, you always multiply by the density. example: If the benzene content is 2.5%v/v, then in 100mL of gasoline, you have 2.5mL of benzene. If the density of Benzene at 15.5°C is 0.81g/mL, then 2.5 x 0.81 = 2.0%w/v.
What is the density of an object has a mass of 20 grams and a volume of 100 cubic centimeter?
The density of the object would be 0.2 grams per cubic centimeter (mass divided by volume).
If aluminum has a density of 2.7 gcm3 what is the volume in cubic centimeters found in 54 grams of aluminum?
To find the volume of 54 grams of aluminum with a density of 2.7 g/cm3, divide the mass by the density: 54 grams / 2.7 g/cm3 = 20 cm3. Therefore, the volume of 54 grams of aluminum is 20 cubic centimeters.
What is the density of a rock that has a mass of 480 grams and a volume of 24 cm3?
The density of the rock is 20 grams/cm3. You can calculate density by dividing the mass by the volume.
