Answer: -
5 : 1 : 3
Explanation: -
Mass of CO₂ = 2.2 g
Molar mass of CO₂ = 44 g / mol
Number of moles of CO₂ =
=
= 0.05 mol
Number of atoms of nitrogen = 6.02 x 10²¹
Number of moles of nitrogen =
=
= 0.01 mol
0.03 gram atom of sulphur means 0.03 moles of sulphur.
Thus the mole ratio of CO₂ : N : S = 0.05 : 0.01 : 0.03
= 5 : 1 : 3
