Expert Answer
All of these statements are correct. Please check one by one.
(a) Molar mass of CO= Atomic mass of C + Atomic mass of O
= 12+16=28 g
So, We can say- 28g of CO contains 12g of carbon and 16g oxygen .
(b) Let's write balanced chemical equation when CO reacts with O2
So, from the stoichiometry of this balanced equation
We can say one mole of CO reacts completely with half mole of O2.
(c)
