The question, as stated, cannot be answered sensibly. A cubic centimetre is a measure of volume, with dimensions [L3]. A gram is a measure of mass, with dimensions [M]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
As a simple mental exercise consider a cm3 of air and of water. They will have very different masses.
Density is grams per cm3. 615/105 = 5.86 g/cm3
density = mass ÷ volume = 4 g ÷ 6 cm3 = 2/3 g/cm3
The density of the object is 3 grams per cm3. This is calculated by dividing the mass (30 grams) by the volume (10 cm3).
Multiply the density (gm cm3) by the volume of the cube (cm3).
180 grams of white tin has a volume of 24.4 cm3, while 180 grams of grey tin has a volume of 32.2 cm3.
The density of ice is approximately 0.92 g/cm3. Therefore, the mass of 2.5 cm3 of ice at freezing temperature would be 2.5 cm3 * 0.92 g/cm3 = 2.3 grams.
First, convert the density from grams per cm3 to kilograms per cm3 (0.768 grams/cm3 = 0.000768 kg/cm3). Then, convert the volume of fuel from liters to cm3 (1 L = 1000 cm3). Finally, multiply the density by the volume to find the mass of the fuel in kilograms (155211 L * 1000 cm3/L * 0.000768 kg/cm3 = 119.25 kg).
The density of the object is 0.5 g/cm3. This is calculated by dividing the mass (40.0 grams) by the volume (80.0 cm3).
"Gram" is a unit of mass. "Cm3" is a unit of volume. So the answer depends on what substance is in the cm3 . If the cm3 is empty, then there are no grams in it. If it's full of air, then there's only a small fraction of a gram in it. If it's a cm3 of water, then there's roughly 1 gram of mass in it. If it's a cm3 of gold, then there are about 19 grams of mass in it.
The density of the marble block is 2.6 g/cm3. This is obtained by dividing the mass (552 grams) by the volume (212 cm3).
The density of poplar, balsam wood is 0.331 grams/cm3. The density of poplar, yellow wood is 0.427 grams/cm3.
Density = Mass/Volume = 21g/2cm3 = 10.5 grams per cm3
