Question

Q3) Calculate the ratio of :-
i) SO₂
ii) SO₃
iii)NO₂
iv)CaO

Answer 1

Explanation:

as we calculate the masses of the given molecules then these will come to be,

SO2=64g

SO3=80g

NO2=46g

CaO=56g

therefore as we calculate the ratio it will come to be,

SO2:SO3:NO2:CaO=32:40:23:28

Answer 2

Answer:

iv)CaO

Explanation:

Option iv is correct answer.
