हिन्दीA given sample of an ideal gas occupies a volume V at a pressure P and absolute temperature T. The mass of each molecule of the gas is m. Which of the following gives the density of the gas?
Correct answer · Option 3
\( Pm/(kT) \)
Explanation
Ideal gas equation: \( P = nkT = \frac{\rho}{m} kT \), where \( \rho = mn \). Therefore, density \( \rho = \frac{Pm}{kT} \).
