QNEET-2016-Ph-1181: NEET 2016 Physics - Class 11 NEET-2016-Ph-1181 Solution: A given sample of an ideal gas occupies a volume V at a…
A 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? P/(kT) Pm/(kT) P/(KTV) mkT
Multiple Choice Options
- A P/(kT)
- B Pm/(kT)
- C P/(KTV)
- D mkT
Step-by-Step Verified Solution
As PV = nRT
_ n = P V R T = m a s s m o l a r m a s s ...(i)
Density, _ = m a s s v o l u m e = ( m o l a r m a s s ) P R T = ( m N A ) P R T
[From eqn. (i)]
_ = m P k T ( _ R = N A k )
