Question

Calculate the density of a sample of gas with a mass of 30 g and volume of 7500 cm3

Answer 1

density=mass/volume
30/7500=0.004

Answer 3

Are you going to contribute at all, orrr? ^

Answer 4

But yes, Abmon is correct.
\[d=\frac{ m }{ v }\]
Where d is density, m is mass, and v is volume. It may be easier to represent it that way.
So putting the numbers in we'd get:
\[d=\frac{ 30g }{ 7500 cm^3 }\]
After putting this I realized that the cubed there might be confusing to someone. So that's just a part of the unit.
\[d=\frac{ 30 }{ 7500 }\]
\[d=0.004\]
I do believe that because of the units we were using we'd have to say that the density is .004g/cm^3
Just to be fancy:
\[.004 g/cm^3\]
