Find The Total Number Of Protons In 10 G Of Calcium Carbonate.

1 mole of CaCO3 = 20 * 1 + 6 * 1 + 8 * 3

= 20 + 6 + 24

= 50.

One mole of CaCO3 contains 50 moles of protons.

10 g of CaCO3 contains:

\(\frac{50 * 10}{100} \)moles of protons

\(\Rightarrow \frac{500}{100}\)

⇒ 5.

Number of protons = 5 * 6.02 * 1023

⇒ 3.01 * 1024 protons.
