Question

Calculate the amount of calcium required to get 112kg of calcium oxide

Answer 1

Answer:

80kg of calcium is required to get 112kg of CaO

Explanation:

G. M. M of calcium oxide(CaO) =40+16=56g

Amount of calcium present in 56g of CaO=40g

Hence, 56g of CaO contains 40g Ca

Thus 112000g of CaO will contain (40*112000)/56

=2000*40=80,000g=80kg(ans)
