Copper is 63.5 and oxygen is 16. They should divide mass by the atomic mass for each element. This will give the number of moles of each. Having done this for both elements, they should find the ratio between the two by dividing them both by the smallest number. The ratio should be close to 1:1 as the formula of copper oxide is CuO. Example ...
