Question

For an ideal gas, number of moles per litre 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

By ideal gas equation
PV=nRT
no.of moles(n) per unit volume(V)
n/V=P/RT

Answer 2

Number of moles per litre in terms of its pressure P, gas constant R and temperature T is $\frac{n}{V}=\frac{P}{RT}$

Explanation:

According to the ideal gas equation:

$PV=nRT$

P = Pressure of the gas

V= Volume of the gas

n=  moles of gas

T= Temperature of the gas in kelvin

R= Gas constant

Thus number of moles per litre in terms of its pressure P, gas constant R and temperature T is :  $\frac{n}{V}=\frac{P}{RT}$
