Explanation:
every two moles of methanol will need three moles of oxygen gas and products 2 miles of carbon dioxide and 4 miles of water
Hydrogen, helium, lithium,
From the equation above the reacting ratio of KClO3 to O2 is 2:3 therefore the number of moles of oxygen produced is ( 4 x3)/2 = 6 moles since four moles of KClO3 was consumed
mass=relative formula mass x number of moles
That is 32g/mol x 6 moles =192grams
