Oxygen gas can be prepared by heating potassium chlorate according to the following equation: 2KC10, (8)→ 2KC1(s) + 302(g) The product gas, O2, is collected over water at a temperature of 20 °C and a pressure of 757.0 mm Hg. If the wet O, gas formed occupies a volume of 5.22 L, the number of moles of KCIO, reacted was 5.3 mol. The vapor pressure of water is 17.5 mm Hg at 20 °C.

Question
Oxygen gas can be prepared by heating potassium chlorate according to the following equation:
2KC103 (8)
2KCl(s) + 302(g)
The product gas,
O2, is collected over water at a temperature of 20 °C and a pressure of 757.0 mm Hg. If the wet
O₂ gas formed occupies a volume of 5.22 L, the number of moles of
KCIO, reacted was 5.3
mol. The vapor pressure of water is 17.5 mm Hg at 20 °C.
