Question

What is the volume in liters of 1.38 mol of ar gas at 400.0 k and 4.00 atm?

Answer 1

Answer:

By ideal gas equation

Volume is 1147.3 litres

Answer 2

The volume of the gas is 11.33 L

Explanation:

To calculate the volume of the gas, we use the ideal gas equation, which is:

PV = nRT

where,

P = pressure of the gas = 4.00 atm

V = volume of the gas = ?

n = number of moles of gas = 1.38 moles

R = Gas constant = $0.0821\text{ L. atm }mol^{-1}K^{-1}$

T = temperature of the gas = 400 K

Putting values in above equation, we get:

$4.00atm\times V=1.38mol\times 0.0821\text{ L.atm }mol^{-1}K^{-1}\times 400K\\\\V=\frac{1.38\times 0.0821\times 400}{4}=11.33L$
