0.01 mole of an organic compound (X) containing 10 % hydrogen, on complete combustion produced 0.9 ~g H ₂ O . Molar mass of ( X ) is _____ g mol ⁻¹ .

Step-by-step solution

Organic compound combustion 0.9 gm H ₂ O mole of H ₂ O = 0.9 18 =0.05 ~mole mole of H in H ₂ O =0.05 2=0.1 mole = mole of H in 0.01 mole Organic compound wt of H atom in 0.01 mole compound =0.1 1=0.1 gm wt of H atom in one mole compound = 0.1 0.01 =10 gm wt . % of H = wt . of H in one mole compound Molar mass of compound 1 aligned & 10= 10 M 100 & M=100 aligned
