This outlines how to determine the mass of lead oxide that can be produced by heating a given mass of lead nitrate. The balanced equation is used to write an expression that shows the number of moles of oxide made from 1 mole of nitrate. The moles are converted to masses in grams. The mass of oxide formed from 1g of nitrate is worked out and this makes it easy to work out the mass of oxide produced from any given number of grams of nitrate.
