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

Solution :

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 :

$Mass \ percentage = \dfrac{mass\ of \ chemical}{total \ mass \ of \ compound}\\\\Mass \ percentage = \dfrac{8}{(8+35)} \times 100 \%\\\\Mass \ percentage = 18.60 \%$

Therefore, the mass percentage of NaNO₃ is 18.60% .
