Answer 1

Answer: 40 %

Ca-1 atom

H-1atom

C-1atom

O-3atom

Explanation:calcium: 40 percent, carbon: 12 percent, and oxygen: 48 percent.1

Answer 2

40.04 %

Explanation:

You take the atomic mass of calcium over the atomic mass ofCaCO3and multiply it by 100 to get the percentage.

The mass of Ca is is 40.078 g; the mass of Cis 12.01 g, and the mass of

3Ois 47.997 g (15.999 g*3)

Add all the masses together to get a total mass of 100.085 g.

40.078g/100.085g

=0.4004 or 40.04%
