The ratio of mass percentage (w/w) of C : H in a hydrocarbon is 12 : 1. It has two carbon atoms. The weight (in g) of CO₂(g) formed when 3.38 g of this hydrocarbon is completely burnt in oxygen is: (Given: Molar mass in g mol⁻¹ C : 12, H : 1, O : 16)

Answer: (B)

Solution

With 2 C (mass 24) and C:H = 12:1, the H mass is 2, i.e. 2 H atoms: the hydrocarbon is
