Question

The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is blank liters

Answer 1

Answer: 18.97 L

Explanation:

This can be solved by the Ideal Gas equation:

$P.V=n.R.T$  

Where:  

$P=2 atm$ is the pressure of the gas  

$V$ is the volume of the gas  

$n=1.5 mole$ the number of moles of gas  

$R=0.0821\frac{L.atm}{mol.K}$ is the gas constant  

$T=35\°C+273.15=308.15 K$ is the absolute temperature of the gas in Kelvin

Finding $V$:

$V=\frac{nRT}{P}$

$V=\frac{(1.5 mole)(0.0821\frac{L.atm}{mol.K})(308.15 K)}{2 atm}$

$V=18.97 L$

Therefore:

The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is 18.97 liters
