Question

56.5 g of sodium nitrate is dissolved in water to make 627 g of solution . what is the percent sodium nitrate in the solution

Answer 1

The percentage of sodium nitrate in the solution is 9.01%

Step-by-step explanation:

Here we have;

56.5 g of sodium nitrate dissolved in water to make a solution of mass = 627 kg

Mass of sodium nitrate, NaNO₃, in the solution = 56.5 g

Mass of resultant solution = 627 g

The relation for the percentage of a solute by mass dissolved in a solvent is presented as follows;

`Percentage \, by \, mass = (Mass \, of \, solute)/(Mass \, of \, solution) * 100`

Therefor, for the 56.5 g of sodium nitrate solution, we have;

`Percentage \, by \, mass \, of \, NaNO_3 = (Mass \, of \, NaNO_3)/(Mass \, of \, solution) * 100 = (56.5 \, g)/(627 \, g) * 100 = 9.01 \%`

Answer 2

9.01%

Step-by-step explanation:

The following data were obtained from the question:

Mass of sodium nitrate, NaNO3 = 56.5g

Mass of solution = 627g

The percentage composition of sodium nitrate, NaNO3 in the solution can be obtained as follow:

Percentage composition of NaNO3 = Mass of NaNO3/mass of solution x 100

Percentage composition of NaNO3 = 56.5/627 x 100 = 9.01%

Therefore, the percentage composition of sodium nitrate, NaNO3 in the solution is 9.01%
