Answer:
25 kg oyegen and 2 kg hydrogen
Explanation:
because when 18kg of water was found the scientist subtracted 2 from 18 then we got 16kg of oxygen so the same formula is applied for the 2nd one as well
Formula
Total amount -2=water, remaining subtraction =2=hydrogen
27kg -2 =25 kg oxygen,=2 hydrogen
