If we take 2.2 grams of co2, 6.02 x 1021 atoms of nitrogen and 0.03 gram atoms of sulphur , then the molar ratio of c, n, and o is .

-

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
