Interpretation Introduction

Interpretation:

The mass of $\text{NaCl}$ obtained by the evaporation of 1 L of sea water should be determined.

Concept introduction:

• Molarity is one of the concentrations expressing terms and it is equal to the moles of solute divided by the liter of solution.

    $\text{Molarity}\text{(M)}\text{=}\frac{\text{Moles}\text{of}\text{solute}}{\text{Liters}\text{of}\text{solution}}$

• $\text{Number}\text{of}\text{moles}\text{=}\frac{\text{Mass}\text{in}\text{grams}}{\text{Molar}\text{mass}\text{of}\text{the}\text{substance}}$
