Question

Calculate the mass percent for each O& H in water knowing that total mass of water is 18 g

mass of hydrogen is 2 g
mass of oxygen is 16 g​

Answer 1

Mass percentage =

`(mass \: of \: element)/(mass \: of \: the \: compound) * 100`

`o = (16g)/(18g) * 100 \\ = 88.9\%`

H =

`(2g)/(18g) * 100 \\ = 11.1\%`
