$\therefore$density of${\text{H}}_2\text{O}\left(\text{l}\right)=\mathrm{1 }\text{g}/\text{m}\text{L}$
$\mathrm{1 }\text{m}\text{L}$contains$=\mathrm{1 }\text{g}{\text{H}}_2\text{O}$
$\mathrm{108 }\text{m}\text{L}$contains$=\mathrm{108 }\text{g}{\text{H}}_2\text{O}$
Number of moles of${\text{H}}_2\text{O}\left(\mathit{\text{l}}\right)=\frac{108}{18}=6$
$\text{H}$has no neutron, Number of neutrons in$\text{O}=16-8=8$
Number of moles of neutrons in$\text{1}$mole of${\text{H}}_2\text{O}=0+8=8$
Number of moles of neutrons in$\text{6}$mole of${\text{H}}_2\text{O}=6\times 8{ }^{}=48$
