Answer 1

Answer:

To find the mass percent of hydrogen in water, take the molar mass of hydrogen in the water molecule, divide by the total molar mass of water, and multiply by 100. Dividing 2.016 by 18.016 gives you 0.1119. Multiply 0.1119 by 100 to get the answer: 11.19 percent.

hope it may help u

please mark it as a brainlist answer

Answer 2

Answer:

THE question is not clear as it is not asked that we have to find the percentage on the basis of mass or volume

hair I am assuming that we have to find it on the basis of VOLUME

Hydrogen percentage

$2 \div 3 \times 100 = 66.66\%$

Oxygen percentage

$1 \div 3 \times 100 = 33.33\%$
