Answer to Question #102364 in General Chemistry for Micah marvelous

Question

What volume of a 25% (w/v) solution of HNO3?

Answer 1

Solution.

$w(HNO3) = \frac{m(HNO3)}{m(solution)} \times 100 \%$

$m(solution) = \frac{m(HNO3) \times 100 \%}{w(HNO3)}$

m(solution) = 50.4 g

$m(H2O) = m(solution) - m(HNO3)$

m(H2O) = 37.8 g

Answer:

m(solution) = 50.4 g
