Chapter 11, Problem 35E

Interpretation Introduction

Interpretation:

The sodium chloride ( $\text{NaCl}$) mass percentage should be calculated for the given diluted solutions.

Concept Introduction:

Mass percent: The mass percent is used as a way of expressing a concentration (or) way of describing a component in a mixture.  Mass percentage is calculated as the mass of a compound divided by the total mass of the mixture multiply by 100.

Molar Mass: The molecular mass is the mass is the molecule, it is calculated as the sum of the atomic weight of each constituent element multiplied by the number of atoms of that element in the molecular formula.

Mass percent in solution: This method to express the concentration (or) the amount of a compound present in a given solution.  The mass percentage of a component in a solution is defined as the mass of solute present per $\text{100 gm}$ of the solution.
