Chapter 13, Problem 115AP

Interpretation Introduction

Interpretation:

If $10.0\text{g}$ of liquid helium at $1.7\text{K}$ is completely vaporized, the volume that helium occupy at STP should be calculated.

Concept Introduction:

The ideal gas equation is as follows:

$\text{P}\text{V}=\text{n}\text{R}\text{T}$

Where, P = Pressure of the ideal gas (atm)

V = Volume of the ideal gas (L)

n = number of moles of ideal gas present (mol)

R = Universal gas constant (L atm/K)

T = Temperature in Kelvin (K)

The condition $0^0\text{C}$ and $1\text{a}\text{t}\text{m}$ are called standard temperature and pressure (STP). Molar volume of an ideal gas is $22.4\text{L}$ at STP.
