Question

At 27°C, one mole of an ideal gas exerted a pressure of 0.821 atm. What is its volume in liters.? (R=0.082 lit - atm/mol-1 K-1)

Answer 1

Volume is 30 L it is based on ideal gas equation

Answer 2

Answer:

The volume in litres is 29.96L.

Explanation:

Given:
Temperature(T): 27°C=27+273=300k

Pressure(P)=0.821 atm

Number of moles(n)=1

To find: Volume in litres(V)=?
Solution:

We know that

For an ideal gas

$PV=nRT$

∴$V=\frac{nRT}{P}$

    =$\frac{0.082*300}{0.821}$

   =29.96L

Therefore, the volume in litres of one mole of an ideal gas at 27°C exerting a pressure of 0.821 atm, when the universal gas constant is 0.082 lit - atm/mol-1 K-1 is 29.96L.
