Answer 2

Hello Sir,,,

Answer Of Your Question☺️☺️
--------------------------------------------

The Molecular Mass Of calcium carbonate,=
$100gmol - 1$

So, Number of Mols(n)=10/100 , =0.1 gmol

ca atoms in a molecules=1

O atoms in a molecules=3

C atoms in a molecules=1

So, Total Number=5

Now,

Protons Of Ca atom=20

Protons Of O atom=8

Protons Of C atom =6

Total Protons,

$20 \times 1 + 6 \times 1 + 8 \times 3 \\ = 50$

Now , Numbers of Protons,,,

$50 \times 6 \times {10}^{22} \\ = 3 \times {10}^{2} + {10}^{22} \\ = 3 \times {10}^{23}$

Hope It Helped✌️✌️✌️✌️
