$\rm\huge\pink\underline\mathfrak\purple</em></strong><strong><em>{</em></strong><strong><em>ANS</em></strong><strong><em>WER</em></strong><strong><em> :-}$

➡ CaCO3 = 40+12+48 = 100g.

CaCO3 ------> Moles

✏ 100g -----> 1

✏ 200g -----> ?

➡ Required moles of CaCO3 = 1× 200/100

Therefore,

➡ Required no. of moles of Ca , C, and O atoms = 2.
