Question

For an ideal gas, a number of moles per liter in terms of its pressure P, gas constant R and temperature T is:

• A. PT/R
• B. PRT
• C. P/RT
• D. RT/P

Answer 1

Answer: (C)

P/RT

According to Ideal Gas Equation, $PV=nRT$

P is the pressure, V is the volume, n is the number of moles, R is gas constant and T is the temperature.

Therefore number of moles per litre,

$\frac{n}{v}$ = $\frac{P}{RT}$

Therefore, C is the correct option.
