Potasium chlorate decomposes to form potassium
chloride and oxygen gas. What volume of oxygen will form if 20.4 g
of the chlorate is heated and the gas is colected at 0.962 atm and
18.3 °C?
Upon heating, potassium chlorate decomposes to potassium
chloride and oxygen gas. The oxygen gas is collected over water at
14.0 °C in a 500.-mL container. If the total pressure is 766
torr,
How many mol of oxygen gas is in the container?
What is the mole fraction of oxygen gas in the container?.
(Mole fraction = mole of substance of interest / mole of the
system)
