Question

chemical formula and molar mass of limestone​

Answer 1

Answer:

Chemical formula- CaCO3

Molar mass-

Ca = 40 x 1 = 40

C = 12 X 1 = 12

O = 16 X 3 = 48

40 + 12+48= 100

The molar mass of limestone (CaCO3) is 100g

Answer 2

Answer:

100g

Explanation:

In CaCo3

here is :-

1 atom of Ca (Calcium), molar mass of 1 Ca = 40g

1 atom of C (Carbon), Molar mass of 1 C = 12g

3 atom of O (Oxygen), molar mass of 3 O = 16x3 = 48g

So, total mass of CaCo3 is 40g + 12g + 48g = 100g
