Density= Mass/Volume
However a cm is a length NOT a volume (volume is cubic cm) so your question as asked can not be answered. However if you meant 21 cubic centimeters, then the density would be 2.71 grams per cc.
The density of the rock is 20 grams/cm3. You can calculate density by dividing the mass by the volume.
The density of the rock is calculated by dividing its mass (56 grams) by its volume. If the volume is unknown, then the density cannot be determined. Density is the mass per unit volume of a substance, so both mass and volume need to be known to calculate it.
Impossible to answer. A volume is not measured in grams it is a cubic amount
Density is a measure of mass per unit volume, so to determine the density of 101 grams, you need to know the volume of the object or material that weighs 101 grams. Once you have the volume, you can calculate the density by dividing the mass (101 grams) by the volume.
To calculate the mass of an object, you can use the formula: mass = density x volume. Multiply the density of the object by its volume to find the mass. Make sure the units for density and volume are compatible, such as grams per cubic centimeter for density and cubic centimeters for volume.
Density is calculated by dividing the mass (in grams) of a substance by its volume (in milliliters or cubic centimeters). The formula for density is: Density = Mass / Volume. By measuring the mass of a sample in grams and the volume in milliliters, you can easily calculate the density of the substance.
Density = Mass/Volume so Volume = Mass/Density. Having said that, density is not measured in grams so it cannot be 0.789 grams. As a result, the question cannot be answered.
Depends on the volume. Density is mass divided by volume.
the mass is the 50 grams you probably need the volume volume = mass / density get the density from tables
Density = Mass/Volume. You cannot calculate density without knowing BOTH mass and volume.
Density = mass/volume, so:36 grams/ 12 milliliters3 grams/ milliliter
The density of the rock is 20 grams/cm3. You can calculate density by dividing the mass by the volume.
density = mass/volume density = 5/10 = 0.5 grams per cubic centimeter
Density = Mass/Volume = 30/15 = 2 grams per millilitre.
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
The density of the rock is calculated by dividing its mass (56 grams) by its volume. If the volume is unknown, then the density cannot be determined. Density is the mass per unit volume of a substance, so both mass and volume need to be known to calculate it.
Density = Mass/Volume = 21g/2cm3 = 10.5 grams per cm3
