Question

find molar mass of calcium carbonate by calculation

Answer 1

ca-40
C-12
O-16
CaCO3=40+12+(16×3)=40+12+48=100u

Answer 2

Answer:

100.0869 g/mol

Explanation:

Molecular weight is the mass of whole molecule.

Steps:- (1) Chemical formula of calcium carbonate ⟶CaCO3

​  

 

(2) Mass of Calcium⟶40

    Mass of Carbon⟶12

    Mass of Oxygen⟶16

(3) Multiply mass of each element by number of atoms of that element.

(4) Add all the masses obtained after multiplication.

⟶CaCO3

​  

 

=1×40+1×12+3×16

=40+12+48

=100.
