Question

51. The mass percentage of oxygen in Caćo, is
(1) 40%
(2) 12%
(3) 16%
(4) 48%​

Answer 1

16% IS THE ANSWER OF THE GIVEN QUESTION

Answer 2

Answer:

48%

Explanation:

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

Caco3

and you know The mass of one mole of calcium carbonate is 100.1 so my answer is element separately, and do this calculation:

mass of element upon

molar mass of compound×100

=, for oxygen, this would be

48.0 upon

100.1

×

100

=

48.0
