Question

There is a 2 m³ of some gas with density 0.9 kg/ m^3. The volume of a gas was increased by factor of two what is its density now

Answer 1

Answer: 0.45 kg/m^3.

Explanation: well i considered the mass to be constant,  so  density*volume = constant.

now using d1v1=d2v2  we get d2 = 0.45 kg/m^3

hope it helps you!
