ANSWER

Mole fraction is defined as the ratio of moles of a particular substance to the total moles of the mixture.

To calculate the moles, we use the equation:

Nummber of moles=

molar mass

given mass

Numbar of moles of HCl=

36.5

3.65

=0.1 mol

Number of moles of water=

18gm/mol

16.2gm

=0.9 mol

Mole fraction of HCl=

mole of water+mole of HCl

mole of HCl

Mole fraction of HCl=

0.9+0.1

0.1

=0.1.

So the answer is 0.10.
