Answer:
1.25mol
Explanation:
moles(n)=mass/Mr
Mr of H2O=(1*2)+16
=18
n=22.5/18
=1.25 mol
1.25 mol
The equation for the calculation of mass is as follows:-
[tex]moles(n)=mass(g)/molar mass(g/mol)[/tex]......(1)
Given:-
Mass of water =22.5 g
Molar mass of water=18 g/mol
Subsitute both the values in the equation (1) as follows:-
[tex]n=22.5\ g/18\ g/mol\\=1.25 mol[/tex]
Hence, the value in moles is 1.25 mol.
