Mass of 18ml water=18gm
no. of moles=
18
18

=1mole
Total molecules=6.023×10
23
×1=6.023×10

One molecule water have 8 neutrons
Total number of neutrons==8×6.023×10
23

=48.16×10

Since m=ρ×V,

m=18 g

Hence number of molecules of H
2

O=1×6.022×10

Number of moles=
18
18

=1

Number of neutrons present in a molecule of H
2

O=2+6=8

Number of neutrons present in 6.022×10
23
molecules of 8×6.022×10

=4.8176×10
