Question

The percentage composition of an organic compound was found to be carbon 14.5% hydrogen 1.8 % chlorine 64.4 6 %oxygen 19.2 4 if the molar mass is 165.5 find the molecular formula

Answer 1

Answer:

Step 1: Percentage composition of the elements present in the compound. Step 2: Dividing by the respective atomic weights Step 3: Dividing the values in step 2 among them by the smallest number. Step 4: Multiplication by a suitable integer to get whole number ratio. ∴ The simplest ratio of the atoms of different elements in the compound. C : H : Cl : O = 2 : 3 : 3 : 2 ∴ Empirical formula of the compound C2H3Cl3O2.Read more on Sarthaks.com - https://www.sarthaks.com/365682/carbon-compound-analysis-following-percentage-composition-carbon-hydrogen-chlorine-oxygen
