Chapter 5, Problem 74P

Interpretation Introduction

Interpretation:

The number of moles of N₂ to raise pressure to 60 in. Hg should be calculated.

Concept Introduction:

The number of moles of the gas can be calculated using ideal gas law.

Mathematically, Ideal gas law states that:

$PV=nRT$

Where,

$P=$ Pressure of the gas in atmospheres ($\text{atm}$).

$V=$ Volume of the gas in liters ($\text{L}$).

$n=$ Amount of the gas in moles ($\text{mol}$).

$R=$ Ideal gas constant.

$T=$ Temperature of the gas in kelvins ($\text{K}$).
