Answer:
Percentage composition = (Mass of the element) ×100/ (Molar mass of the compound)
Mass of Carbon = 12
Mass of Hydrogen (H) = 1
Molar mass of compound =[(2×12 )+ 5 + 16 + 1] = ( 46 + 5 + 16 + 1) = 46 %
Composition of Carbon
= ( 24 x 100) / 46 = 52.17 %D = 52.2 %
Composition of Hydrogen
= (6 x 100) / 46 %3D = 13.04 %

Answer:
Explanation:
mass percentage of carbon = mass of carbon/ total mass ×100
= (2×12)/46 ×100
=(24/46) × 100
=52.17%
mass percentage of hydrogen= mass of hydrogen / total mass ×100
=(1×6) / 46 ×100
=13.04%
