Question

A sample contains 3 mol of H2O. Find
1. Total number of molecule in the sample
2. Total number of atoms in the sample
3. Total number of H atoms in the sample
4. Total number of O atoms in the sample

Answer 1

mate here is your answer...

Given 3 moles of H2O is present.

answers:-
1.total number of molecules=6.022*10^23
2.total number of atoms=

6.022*10^23* atomicity=
(6.022*10^23)*3=18.066*10^23

3.total number of hydrogen atom
=2* 6.022*10^23
=12.044*10^23

4.total number of O atom=
6.022*10^23
