A sample of oxygen gas is collected over water. The volume of gas collected is 0.250 L at 26°C and 765 torr total pressure. (Water vapor
pressure at 26°C = 25.22 torr)

How many grams of oxygen gas are collected?

If the oxygen gas collected is the product of decomposition of
potassium chlorate, how many grams of potassium chlorate is
decomposed (assuming 100% yield)?

0.317g, 0.810g

how do I set the problem up?

Pbco3 –> pbo+ co2. how many liters of carbon dioxide gas is produced from the decomposition of 32 grams of lead (ll) carbonate?
