A total of 1.4 moles of sodium nitrate is dissolved in enough water to make 2.0 liters of an aqueous solution. The gram-formula mass of sodium nitrate is 85 grams per mole.

·Write the chemical formula for the solute in the solution.

Show a numerical setup for calculating the mass of the solute used to make the solution.

Compare the boiling point of the solution at standard pressure to the boiling point of H2O at standard pressure.

Determine the molarity of the solution.

The chemical formula of the solute is NaNO3. The mass of this is 1.4*85=119 g. The boiling point of the solution is higher than water. The molarity of this solution is 1.4/2=0.7 M.
