The mass of sulphuryl chloride which contains 14.2 g chlorine is

1. 27 g
2. 135 g
3. 13.5 g
4. 260 mg.

The molecular formula of sulfuryl chloride is :SO₂Cl₂
​The molar mass of sulfury chloride = 135 g/mol
​1 mol SO₂Cl₂ molecule contain 2 mole of Cl atoms.
Mass of 2 moles of Cl atom = 2 x molar mass of Cl
                                          = 2 mole x 35.5 g/mol
                                         = 71 g
71 g of Cl is found in 135 g SO₂Cl₂
So, 14.2 g Cl can be obtained from = 135 g of SO₂Cl₂/71 g of Cl​ x 14.2 g of Cl
​                                                       = 27 g of SO₂Cl₂

So the correct option is 1.
