Determine the molecular formula of alkyne, the mass fraction of carbon in which is 90%, hydrogen 10%, The relative density of the substance for hydrogen is 20.
Let’s find the molar mass of the substance – M = D * M (H2) = 20 * 2 = 40
Let’s find the molar mass of carbon – w * M = 0.9 * 40 = 36
Formula – C3H4 – propyne (general formula of the CnH2n-2 series)
