% of hydrogen=(2/18) multiplied by 100

% of water=(16/18) multiplied by 100 please try to solve now

Answer 2

Answer:

Mass% of an element =

$\frac{mass \: of \: that \: elment \: in \: the \: ompoun \: \times 100}{molar \: mass \: of \: the \: compound}$

Molar mass of water % 18.02g

Mass of hydrogen =

$\frac{2 \times 1.008 \times 100 }{18.02}$

Mass% of oxygen =

$\frac{16.00 \times 100}{18.02} = 88.79$
