Problem 1.2A compound contains 4.07% hydrogen,24.27% carbon and 71.65%

1.	Problem 1.2A compound contains 4.07% hydrogen,24.27% carbon and 71.65% chlorine. Itsmolar mass is 98.96 g. What are itsempirical and molecular formulas?
Answer» total mass = 98.96 , assume it to be 100 for easy calculation now mass of H = 4% = 4g = 4/1= 4 molesmass of C = 24% = 24g = 24/12 = 2 molesmass of Cl = 71% = 71g = 71/35.5 = 2 moles so molecular formula = C2H4Cl2 and emperical formula =CH2Cl

Answer»

total mass = 98.96 , assume it to be 100 for easy calculation

now mass of H = 4% = 4g = 4/1= 4 molesmass of C = 24% = 24g = 24/12 = 2 molesmass of Cl = 71% = 71g = 71/35.5 = 2 moles

so molecular formula = C2H4Cl2

and emperical formula =CH2Cl
