Chapter 19, Problem 14QAP

Interpretation Introduction

Interpretation:

The mass percent of Cl in the sulfate salt of given complex ion is to be calculated.

Concept introduction:

Molar mass is defined as average mass of atoms present in the chemical formula. It is the sum of the atomic masses of all the atoms present in the chemical formula of any compound. Mass percentage of an element in a given complex ion is calculated by dividing the mass of the element present in the given complex ion to the mass of the complex ion.

The formula to calculate mass percent for each element in a given complex ion is as follows:

$\text{Mass percentage =}\frac{{\text{m}}_{\text{(element)}}}{{\text{m}}_{\text{(complex ion)}}}\text{×100}$
