Answer 2

The percentage of carbon is 14.8%.

Given: $Ca(HCO_3)_2$

To find: The percentage of carbon.

Solution:

The given compound is $Ca(HCO_3)_2$.

The atomic mass of Ca is 40.

The atomic mass of C is 12.

The atomic mass of H is 1.

The atomic mass of Oxygen is 16.

Thus the molar mass of $Ca(HCO_3)_2$ will be-

$40 + (1 + 12 + 3 \times 16) \times 2 \\ 40 + 61 \times 2 \\ = 162$

The total mass of carbon is 12×2=24 gram.

Thus the percentage of carbon atom will be-

$\frac{24}{162} \times 100 = 14.8\%$

The percentage of carbon is 14.8%.
