Answer:

We know that calcium and oxygen react in a fixed ratio of 5:2, by mass, to produce 7g of calcium oxide. When 5g of calcium react with 20g of oxygen, the same amount of calcium oxide will be formed. Therefore, 7g of calcium oxide will be formed when 5g of calcium will react with 20g of oxygen.
