Question

convert 100 grams of calcium carbonate into mole​

Answer 1

Explanation:

Given mass of CaCO3 = 100g

CaCO3 mass,,,

◾Ca= 40u

◾ C = 12u

◾O = 16u

No. of moles = Given mass

Molar mass

= 100 = 1 mol

100

To find the molecular mass , , you have to add up the molar masses of Ca,, C and O3...

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

So,, the molar mass of CaCO3 is :-

= 40.1+12+16

= 100.1 g/mol
