Chapter 6, Problem 6.140CHP

Interpretation Introduction

Interpretation:

The mass ratio of two components in the mixture has to be calculated.

Concept introduction:

Number of moles:

One mole is the equal to number of atoms in $\text{12g}$ of carbon $\text{-12}$ which is equal to $\text{6}{\text{.023×10}}^{\text{23}}$ atoms. This is also known as Avogadro number.

Number of moles = $\frac{\text{given}\text{mass of the element}}{\text{atomic}\text{mass}\text{of}\text{element}}$

Number of grams of compound = number of moles of compound $\text{×}$ atomic mass of compound
