The mass percent and molarity of NaCl is to be calculated. Concept Introduction: There are many ways to determine the concentration of the solution. One of the most used methods is molarity. Molarity may be defined as the number of moles of the solute in one liter of the whole solution. Thus, the molarity can be calculated as, M = moles of solute ( mole ) total volume of solution ( L ) The mass percent of a solution can be calculated using formula, Mass percent = Mass of solute Mass of solution × 100 % .

Interpretation Introduction

Interpretation:

The mass percent and molarity of NaCl is to be calculated.

Concept Introduction:

There are many ways to determine the concentration of the solution. One of the most used methods is molarity. Molarity may be defined as the number of moles of the solute in one liter of the whole solution. Thus, the molarity can be calculated as,

M=moles of solute (mole)total volume of solution (L)

The mass percent of a solution can be calculated using formula,

Mass percent=Mass of soluteMass of solution×100%.
