Answer 2

Assume you have 100g of the substance ---> 74.9g Carbon, 25.2g Hydrogen

Divide by the molar mass

Divide each molar quantity by the smaller molar quantity

If you get ~ whole numbers, that's your ratio. If not, multiply by a fraction to convert them to whole numbers.

Answer 3

is the answer C4H? @vocaloid

Answer 4

74.9g Carbon = 6.24 moles C
25.2g Hydrogen = 25.00 moles H

dividing

6.24 moles C/6.24 = 1 mol C
25.00 / 6.24 = 4 moles H

CH4, not C4H
