A 8.15 g sample of hydrogen peroxide (H2O2) decomposes to form water and oxygen. The temperature and pressures conditions in the lab were 21.2oC and 761.4 torr, respectively. The oxygen gas is collected over a sample of water at 21.2oC; the vapor pressure of water at that temperature is 18.9 torr. When the water level inside and outside of the tube is equal the volume of of gas is recorded as 176.23 mL.

a) Write and balance the equation for the decomposition reaction

b) What is the partial pressure of the oxygen gas?

c) How many moles of oxygen gas were produced?

d) What was the mass of hydrogen peroxide that reacted?

e) What is the percent by mass of the hydrogen peroxide from the original sample?
