Question

Total number of protons in a 10gm of calcium carbonate​

Answer 1

Answer:

In total, one molecule of calcium carbonate has #20+6+24=50# protons. But, we have #6.02*10^22# molecules of calcium carbonate. Therefore, in total, we would have #6.02*10^22*50=3.01*10^24# protons.

Answer 2

Explanation:

molar mass of CaCO3 =40 + 12 + 16×3

52+48=100

no. of mole of CaCO3 = 10÷100

=0.1

no. of atom in the compound = 5

( 20 + 6 +24)×0.1 × 6.023 × 10²³
