We’re being asked to calculate the molarity (M) of a hydrogen peroxide (H2O2) solution.
Recall that molarity is the ratio of the moles of solute and the volume of solution (in liters). In other words:
We’re given the mass percent of H2O2 in water, 3.0%. Recall that mass percent is given by:
This means in 100 g of solution, we have 3.0 g H2O2.
The steps we need to do for this solution are:
Step 1: Calculate the moles of H2O2
Step 2: Calculate the volume of the solution (in L).
Step 3: Calculate the molarity of the solution.
Household hydrogen peroxide is an aqueous solution containing 3.0% hydrogen peroxide by mass. What is the molarity of this solution? (Assume a density of 1.01 g/mL.)
