Answer:
no. of moles = mass given/ molar mass
=400/100= 4 moles of caco3
Explanation:
molar mass of caco3
Ca= 40
C=12,O= 16
therefore,caco3=40+12+16×3=100

Answer:
4 moles
Explanation:
Molecular weight of CaCO3 =40+12+(3×16)=100g
Given weight of CaCO 3 =400g
As we know that,
No. of moles = Molecular weight/Given weight
Therefore,
No. of moles in 400gCaCO3 = 400/100
=4 moles
