Answer 2

Quicklime chemical formula is CaO.

• The molar mass of calcium, Ca is 40 g.
• The molar mass of oxygen, O is 16 g.
• Therefore molar mass of quicklime is 56 g.
• If one mole of quicklime has 56 g mass, then two moles of quicklime will have the following mass-

1 CaO = 56 g

2 CaO = 2 x 40 + 2 x 16

2 CaO = 80 + 32

2 Cao = 112 g

The mass of two moles of quicklime is 112 g.
