Question

Percentage of oxygen in calcium carbonate with full process

Answer 1

Answer:

oxygen makes a 48% of the mass of caco3

Explanation:

the mass of one mole of calcium carbonate is 100.1g of the mass

40.1g is due to the one mole of calcium atoms it contains

12.0g is due to one mole of carbon in it

48.0g is due to the 3 moles of oxygen atoms in one mole of caco3

To find percent composition

mass of element\molar mass of compound×100

48.0/100.1×100=48%

Answer 2

Percentage of oxygen in calcium carbonate is 48 percent.....

Calcium carbonate is CaCO3 Atomic mass Ca=40 C=12 O3=(16)3=48

Total mass of CaCO3=100

Now percentage of O3 is (48÷100)×100

Which is 48%.....
