Chapter 5, Problem 5.42P

Interpretation Introduction

Interpretation: The mass of aluminum reacting with excess HCl to form AlCl₃ and H₂ gas needs to be determined.

Concept Introduction: An ideal gas equation is represented as follows:

  $PV=nRT$

Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature of the gas.

Number of moles can be calculated from mass and molar mass as follows:

  $n=\frac{m}{M}$

Here, m is mass and M is molar mass.
