Answer 1

Answer:

Solution : Mass percent of hydrogen in water `(H_(2)O)=(2xx100)/(18)=11.11` <br> mass percent of oxygen in water `(H_(2)O)=(16xx100)/(18)=88.89`

Answer 2

Answer:

1) Find the molar mass of all the elements in the compound in grams per mole.

2) Find the molecular mass of the entire compound.

3) Divide the component's molar mass by the entire molecular mass.

4) You will now have a number between 0 and 1. Multiply by 100% get percent composition.
