Out of 100 g, C is 40g, H is 13.33g and N is 46.5 g. Therefore, no of moles (C) = 40/12 = 3.33// No of moles (H) = 13.33// No of moles of N = 46.67/14 = 3.315// The ratio = 3.33:13.33:3.33 = 1:4:1 (approx.). Therefore, empirical formula, I believe, is CH4N//

Vasudha Vasudha 3 years, 10 months ago

Industrial Method of Preparation Hydrogen peroxide is prepared by the electrolysis of 30% ice-cold H2SO4. When acidified sulfate solution is electrolyzed at high current density, peroxodisulphate is obtained. Peroxodisulphate is then hydrolyzed to get hydrogen peroxide. Boiling Point: 150.2 °C Molecular Weight/ Molar Mass: 4.0147 g/mol Density: 1.05 g/cm3 Melting Point: -0.43 °C
