Answer» tion:step 1Divide the given percentages of atoms with their molecular massesH---4.07/1 =4.07C---24.27/12 =2.02Cl--71.65/35.5=2.01step 2DIVIDE all values with the lowest VALUE obtained. H---4.07/2.01=2 C---2.02/2.01=1 Cl---2.01/2.01=1therefore the EMPIRICAL formula isCH 2 ClWEIGHT OF EMPIRICAL FORMULA=12+2+35.5=49.5Given molecular weight =98.96 which is double of empirical weight .therefore molecular formula is C 2 H 4 Cl 2 .HOPE it will help you |
