Density = mass / volume
therefore, both mass and volume are needed
the first one represents volume
The Space it occupies is the answer

Explanation:
Think about it this way, potential energy is stored energy while kinetic energy is active energy.
<span>mass B/molar mass A = (rate A/rate B)^2.
we know our unknown gas (A) effuses at .797 times our known gas (B) so
rate A/rate B = .797
so 0.797^2 = 28 / molar mass A
Molar mass A = 28 / 0.635 = 44.09 g / mole
Molar mass is 44.09 g/mol</span>
