Question

A compound contains 5.07% hydrogen, 26.27% carbon and 72.65% chlorine. Its molar mass is 98.96. What are its empirical formula amd molecular formulas ?​

Answer 1

Explanation:

step 1

Divide the given percentages of atoms with their molecular masses

H---4.07/1 =4.07 C---24.27/12 =2.02

CI--71.65/35.5=2.01

step 2

divide all values with the lowest value obtained.

H---4.07/2.01=2

C---2.02/2.01=1

CI---2.01/2.01=1

therefore the empirical formula is

CH₂Cl

WEIGHT OF EMPIRICAL

FORMULA=12+2+35.5=49.5

Given molecular weight =98.96 which is double of empirical weight.therefore molecular formula is C₂H4Cl2.

Answer 2

Answer:

98.96 is ur answer
