Answer» A hydrocarbon contains 80% carbon.What is the empirical FORMULA of the compound is CH3Explanation:given a hydrocarbon contains 80% of C. That means hydrogen will be 20%Atomic mass of carbon = 12 atomic mass of hydrogen=1moles of carbon= 80/12=6.67moles of hydrogen= 20/1= 20since SMALLEST value is 6.67 by DIVIDING we get RATIO of C:H as 1:3so empirical formula is CH3 |
