The answer to your questions is 14.3kg. You have to first add the oxygen and hydrogen element total together, and then subtract that from your total of 50kg. Then you will get an answer of 14.3kg.

50-(30.8+4.9)=14.3 kg.
You start with 50 then you need to subtract 30.8 and 4.9 from it. So you add them together and get 35.7. Then you subract 25.9 from 50 and get 14.3 kg.
