  1. Calculate the pOH of a solution prepared by dissolving 4.50 g of HNO3 in 850 mL of solution.
Expert Solution
Step 1

First determine molarity of the solution, from that determine pOH of the solution.

Molarity = moles of HNO3volume of solution in L

Moles of HNO3 = mass of HNO3molar mass of HNO3=4.50 g63.01 g/mol=0.07142 mol

Volume of solution is 850 mL = 0.850 L
