Calculate the mass percentage of each element in water `(H_(2)O)`

Text Solution

Verified by Experts

Molar mass of `H_(2)O=2+16=18g`
(i) Mass of percentage of H atoms in `H_(2)O=(2xx"Atomicmass ofH")/("Molecular mass of" H_(2)O)xx100`
`=(2xx1)/(18)xx100=11.11%`
(ii) Mass percentage of O atom in `H_(2)O=(1xx"Atomicmass of H")/("Molecular mass of" H_(2)O)xx100`
`=(16)/(18)xx100=88.89%`
