Chapter 18, Problem 18.47SP

Interpretation Introduction

Interpretation:

It should be determined that the $Ca{H}_2$ in kilogram which is needed to produce $\text{2}\text{.0}\text{×}{\text{10}}^{\text{5}}\text{L}\text{of}{\text{H}}_{\text{2}}$ gas at ${25}^{o}C$ and $1.00atm$ pressure.

Concept introduction:

•                   $\text{Number}\text{of}\text{mole}\text{=}\frac{\text{Given}\text{mass}\text{of}\text{the}\text{substance}}{\text{Molar}\text{mass}}$
• The molar mass of an element or compound is the mass in grams of 1 mole of that substance, and it is expressed in the unit of grams per mol (g/mol).
• For chemical reaction balanced chemical reaction equation written in accordance with the Law of conservation of mass.
• Law of conservation of mass states that for a reaction total mass of the reactant and product must be equal.
• Stoichiometric factor is a relationship between reactant and product which is obtained from the balanced chemical equation for a particular reaction.
• $PV=nRT$ This equation is known as ideal gas equation.
• $n=\frac{PV}{RT}$
