The percentage composition of this compound : 40%Ca, 12%C and 48%O

Further explanation

Given

20.0 g of calcium,

6.0 g of carbon,

and 24.0 g of oxygen.

Required

The percentage composition

Solution

Total mass of compound :

=mass calcium + mass carbon + mass oxygen

=20 g + 6 g + 24 g

=50 g

Percentage composition :

  • Ca-calcium

[tex]\tt \dfrac{20}{50}\times 100\%=40\%[/tex]

  • C-carbon

[tex]\tt \dfrac{6}{50}\times 100\%=12\%[/tex]

  • O-oxygen

[tex]\tt \dfrac{24}{50}\times 100\%=48\%[/tex]
