Question

Calculate the mass percent of a solution that is composed of 8.00 g NaNO3 dissolved in 35.0 g of water.

Answer 1

The mass percent of NaNO₃ is 18.60% .

To Find :

The mass percent of a solution that is composed of 8.00 g NaNO3 dissolved in 35.0 g of water.

Solution :

Mass percentage is given as :

`Mass \ percentage = (mass\ of \ chemical)/(total \ mass \ of \ compound)\\\\Mass \ percentage = (8)/((8+35)) * 100 \%\\\\Mass \ percentage = 18.60 \%`

Therefore, the mass percentage of NaNO₃ is 18.60% .
