NEET · Physics · STD 11 - 12 . kinetic theory of gases
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 \(?\)
- A \(\frac{P}{{kTV}}\)
- B \(mKT\)
- C \(\;\frac{P}{{kT}}\)
- D \(\;\frac{{Pm}}{{kT}}\)
Answer & Solution
Correct Answer
(D) \(\;\frac{{Pm}}{{kT}}\)
Step-by-step Solution
Detailed explanation
As \(P V=n R T\) or \(n=\frac{P V}{R T}=\frac{\text { mass }}{\text { molar mass }}\) \(. . .(i)\)
