73. A 500.-mL sample of O2 gas at 24 °C
was prepared by decomposing a 3%
aqueous solution of hydrogen peroxide,
H2 O2, in the presence of a small amount
of manganese catalyst by the reaction
2H2 O2 (aq) → 2H2O (g) +
The oxygen thus prepared was
collected by displacement of water. The
total pressure of gas collected was
755 mm Hg. What is the partial pressure
of O2 in the mixture? How many moles
of O2 are in the mixture? (The vapor
pressure of water at 24 °C is 23 mm Hg.)

A 0.8765 g sample of impure sodium chlorate was heated until the production of oxygen gas ceased. The oxygen
gas collected over water occupied 57.2 ml at a temperature of 22 °C and a pressure of 734 torr. Calculate the mass
percent of NaCIO3 in the original sample. (At 22 °C the vapor pressure of water is 19.8 torr.)
A sample of 3.73 mol of argon is confined at low pressure in a volume at a temperature of 61 C. Describe

molecule in the gas, and the root-mean-square speed.
(a) The temperature is increased to 177 °C.
(b) The volume is tripled.
(c) The amount of argon is decreased to 1.96 mol.
Give each answer as a decimal factor of the form: new value = factor old value. A factor of 1 means no
