The catalytic decomposition of hydrogen peroxide yields oxygen gas and water, according to the reaction given below. In an experiment, the decomposition of hydrogen peroxide yielded 75.3 mL of gas collected over water at 25°C and 0.976 atm. (Pwater = 0.032 atm at 25°C)

2 H2O2(aq) → 2 H2O(l) + O2(g)

If the original H2O2 solution had a volume on 500 mL, what was the molar concentration of hydrogen peroxide prior to decomposition?

A)    1.8 * 10-4 M
B)    0.058 M
C)    0.0062 M
D)    0.060 M
E)    0.012 M

Given:

Volume of hydrogen peroxide=75.3 mL

Temperature= 25oC

Pressure=0.976 atm

Volume of original hydrogen peroxide=500 mL

Pressure of water=0.032 atm

Conversion:

From mL to litres:

Volume of hydrogen peroxid...
