Chapter 8, Problem 33E

Interpretation Introduction

(a)

Interpretation:

The mass in grams for $1.05\text{L}$ of hydrogen sulfide, ${\text{H}}_{\text{2}}\text{S}$ is to be calculated.

Concept introduction:

A mole of a substance is defined as the same number of particles of the substance as that present in $12\text{g}$ of ${}^{12}\text{C}$. The number of particles present in one mole of a substance is $6.023\times {10}^{23}$ particles.
