A sample of a perfect gas occupies a volume V at a pressure P and obsolete temperature T. The mass of each molecules is m, which of the following expression given the number of molecules in the sample?

Options

A. `(PV)/(m)`
B. `(k)/(PVT)`
C. `(m)/(k)`
D. `(PV)/(kT)`

Answer

D

Explanation

`PV = mu RT, PV = n/N xx h Nt or n=(PV)/(kT)`.
