We have to calculate the mass of hydrogen (in grams) in 100.1-g sample of compound that contains 11.86 % hydrogen by mass.
Mass percent of an element in a compound can be calculated using this formula:
A compound isolated from the rind of lemons is found to be 88.14 % carbon and 11.86 % hydrogen by mass.
How many grams of H are there in a 100.1-g sample of this substance?
