(B) The molar mass of $CaCO_3$ is $100 \ g/mol$.$10 \ g$ of $CaCO_3 = \frac{10}{100} = 0.1 \ mol$ of $CaCO_3$.Each molecule of $CaCO_3$ contains $20 (Ca) + 6 (C) + 3 	imes 8 (O) = 50$ protons.Total moles of protons = $0.1 \ mol 	imes 50 = 5 \ mol$ of protons.Total number of protons = $5 	imes 6.022 	imes 10^{23} = 3.011 	imes 10^{24}$.

The total number of protons in $10 \ g$ of $CaCO_3$ is = ......
