Question

The strengths of  volume hydrogen peroxide (density ) in terms of mass percentage and molarity (M) respectively are: (Molar mass of )

Canvas Classes · Accepted Answer

Strategy:
 "5.6 volume" means 1 L of solution produces 5.6 L of  at STP. Use the molar volume () to find the moles of  and its concentration.

Step 1: Calculate molarity
.
Since 1  comes from 2 :
.

Step 2: Calculate mass percentage
Mass of  in 1 L .
Since density , mass of 1 L solution .
