The reaction 2KCIO3 (s) 2KCI (s) + 302 (g) represents a common laboratory procedure for producing small quantities of pure oxygen. A 0.250-L flask is filled with O2 that has been collected over water at an atmospheric pressure of 729 torr. The temperature of the water and the gas is 14 °C. Calculate the molar volume of oxygen at 0 °C and 760 torr. Note: The vapor pressure of H2O at 14.0 °C is 12.0 torr. Hint: "molar volume" is expressed as L/mol

Question
The reaction
2KCIO3 (s) 2KCI (s) + 302 (g)
represents a common laboratory procedure for producing small
quantities of pure oxygen. A 0.250-L flask is filled with O2 that has
been collected over water at an atmospheric pressure of 729 torr.
The temperature of the water and the gas is 14 °C.
Calculate the molar volume of oxygen at 0 °C and 760 torr.
Note: The vapor pressure of H2O at 14.0 °C is 12.0 torr.
Hint: "molar volume" is expressed as L/mol
