Chapter 9.4, Problem 9.13P

Interpretation Introduction

Interpretation:

The molecular weight of the gas produced during the reaction of $\text{HCl}$ with ${\text{Na}}_{\text{2}}\text{S}$ has to be calculated.

Concept Introduction:

Ideal gas equation is an equation that is describing the state of an imaginary ideal gas.

$\text{PV}\text{=}\text{n RT}$

Where,

P is the pressure of the gas

V is the volume

n is the number of moles of gas

R is the universal gas constant $\text{(R=0}{\text{.0821LatmK}}^{\text{-1}}{\text{mol}}^{\text{-1}})$

T is the temperature

Molar mass: The molar mass of the sample is defined as the mass of the sample per mole.

Molar mass =$\frac{\text{mass}\text{of}\text{the}\text{sample}}{\text{number}\text{of}\text{moles}\text{of}\text{sample}}$
