Question

100 grams of CaCo3 how many moles?​

Answer 1

Answer:

It is one mole

Explanation:

Ca=40 gms

C=12 gms

O=16 gms

therefore O 3=48 gms

Answer 2

Answer:

given mass of CaCO3  

=100g

CaCO3 mass Ca = 40u, C =1 2u, O = 16u

No. of moles

=Given mass /molar mass                        

=100/100                      

=1 mol

To find the molecular mass You add up molar masses of Ca, С and o3

They are 40.1, 12 and 16 g/mol respectively.

So the molar mass of CaCO3 is:-

= 40.1 + 12 + 3 x 16

=100.1 g/ mol.
