General Chemistry

Question #115890

A 32 mL solution of HNO3 has a concentration of 0.476 M. Calculate the pH and then
calculate the mass in grams of HNO3 in solution.

Expert's answer

"pH = -log[H+]."

PH=_ log(0.476)

PH= 3.2

The mass in solution is given by;

"Mass=moles *rfm"

Mass=0.476*63= 30g
