Question

Find the No. of GMM in
100g CaCo3​

Answer 1

Answer:

100g/mol

Explanation:

Molar mass of Calcium - 40

Malar mass of Carbon - 12

Molar mass of Oxygen - 16x3= 48

so

total Gram Molecular Mass (GMM) of CaCO3 is 100g/mol.

Can somebody tell me what is GMM so that I could correct my answer if it is wrong?

Answer 2

Explanation:

Step 1:

Given mass of CaCO3 =100g

️ Mass of CaCO3; Ca=40u, C=12u, O=16u

Step 2:

️No. of moles=Given mass /molar mass

=100/100

=1mol

Step 3:

️ Now, we find the molecular mass to 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:-

So the molar mass of CaCO3 is:-= 40.1+12+3x16

So the molar mass of CaCO3 is:-= 40.1+12+3x16=100.1 g/mol.
