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
The density of the 6 cm3 block of ice is approximately 0.67 grams/cm3. This can be calculated by dividing the mass (4 grams) by the volume (6 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.
"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.
1.532 grams / 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
Density = mass/volume = 106.8/12 grams/cm3 = 8.9 grams/cm
180 grams / 30 cm3 = 6 g/cm3.
Density = mass / volume = 12.9 grams / 8 cm3 = 1.6125 = rounded to one significant figure = 2 grams/cm3.
3.0 g/cm3
