Question

Compressibility factor for 2 mol of an ideal gas:

• A. $2$
• B. $1$
• C. $0$
• D. $\infty$

Answer 1

The correct option is B $1$

Compressibility factor:- It is also known as the compression factor or the gas deviation factor, which describes the deviation of a real gas from ideal gas behaviour. It is simply defined as the ratio of the molar volume of a gas to the molar volume of an ideal gas at the same temperature and pressure.

$Z=\frac{PV}{nRT}$

$Z=1$, for ideal gas it does not depend on number of moles of gas.

Compressibility factor for $2$ mol of an ideal gaas is $1$.
