Question

If 25g of calcium carbonate is heated calculate the number of moles of calcium carbonate used

Answer 1

`\huge\mathfrak{Solution :- }`

★ Molecular weight of Calcium carbonate (CaCO)

=> 40+12+(16×3)

=> 100 g

Given,

Weight : 25g

Therefore,

Number of Moles

`= > (Weight)/(Molecular \:mass)`

`= > (25)/(100)`

`= > 0.25 \: moles`

★Hence, O.25 moles of calcium carbonate used.
