Step 1

Given information:

Volume of gas cylinder = 55.0 L

Temperature = 30 °C

Moles of nitrogen gas = 3.238 mol

Total pressure = 2.14 atm

Step 2

Ideal gas law gives the empirical relationship between pressure, volume, temperature, and amount of gas that is number of moles of a gas. The ideal gas equation is represented as follows:

Step 3

Using ideal gas equation first total moles o...
