Question

Calculate the mass of CO2 that has the same number of molecules as there are in 16g of SO2.
i want the proper answer plz​

Answer 1

Mass of sulphur dioxide = So 1 mole = 64 g of sulphur dioxide

Therefore 16 g of sulphur dioxide = 1 × 16 = 1/ 4 mole

                                                    64

Now, 1 mole of oxygen = 32 g

So 1/4 mole of oxygen = 32   × 1/4 = 8 g

So 8 g of oxygen will contain the same number of molecules as 16 g of sulphur dioxide.
