What is the empirical formula of a compound composed of 81.71% C and 18.29% H by...
Homework Answers
Suppose we have 100 grams of sample
Mass of carbon = 81.71 grams
Moles of C = mass / molar mass
= 81.71 / 12
= 6.81
Mass of hydrogen = 18.29 grams
Moles of H = 18.29 / 1
= 18.29
Simplest ratio of C: H
= 6.81 : 18.29
= 3:8 ( integer form )
So empirical formula
C3H8
