Question

What is the volume, in liters, occupied by 1.73 moles of N2 gas at 0.992 atm pressure and a temperature of 75º C? (R value- 0.08206)

Answer 1

Volume of the nitrogen gas = 49.8 L

Explanation:

It is given that the pressure, number of moles and temperature of nitrogen gas, and gas constant value being constant and it is taken as 0.08206 L atm mol⁻¹K⁻¹.

Temperature = T = 75°C = 75 + 273 = 348 K

Pressure = P = 0.992 atm

Number of moles = n = 1.73 moles

We have to use the ideal gas equation, PV = nRT, and rearranging the equation to get Volume in litres.

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

 = $\frac{1.73\times 0.08206\times348}{0.992}$

= 49.8 L

So the volume of Nitrogen gas = 49.8 L
