Chapter 11.8, Problem 11.65QAP

Interpretation Introduction

(a)

Interpretation:

The volume in liters of hydrogen at $0°\mathrm{C}$ and 1 atm should be determined.

Concept Introduction:

Ideal gas law gives the relationship between pressure (P), volume (V), temperature (T) and amount of gas or number of moles (n).

The equation for Ideal gas law is:

PV = nRT

Where, P = pressure of a gas

V = volume of a gas

n = number of moles of a gas

T = temperature of a gas

R = Ideal gas constant ( $0.082057L{\text{ atm mol}}^{-}{}^1{\text{K}}^{-}{}^1$ )

Number of moles is defined as the ratio of given mass to the molar mass.

The mathematical expression is given by:

  $\text{Number of moles =}\frac{\text{Given mass}}{\text{Molar mass}}$

Interpretation Introduction

(b)

Interpretation:

The mass of magnesium in grams which is required to prepare 5.00 L of hydrogen at 735 mmHg and 18°C should be determined.
