How many grams of hydrogen are in 92 g of ch4o?

The answer to this question would be: 11.5 grams

The molecular mass of hydrogen is 1, oxygen is 16 and carbon is 12. Then the molecular mass of CH4O would be: 12 + 4 (1) + 16 = 32.

To find the hydrogen mass, you just need to divide the hydrogen with total mass, resulting in the mass ratio of hydrogen to the compound. Then the amount of hydrogen inside 92 gram of CH4O are: 92grams * (4/32) = 11.5 grams
