The mole fraction of NaCl in an aqueous solution is 0.132. What is
the weight/weight percent of NaCl in
this solution?
Molar Mass
NaCl: 58.44 g/mol
H20: 18.016 g/mol
Hint: Remember to give your answer as a percent!

The weight/weight percent(%w/w) of NaCl in  solution : 33.03%

Given

Mole fraction of NaCl : 0.132

Required

The weight/weight percent of NaCl

Solution

1 mol solution : 0.132 mol NaCl + 0.868 mol H₂O

mass NaCl :

mass H₂O :

Total mass = 7.714 + 15.64 = 23.354 g

the product of the pressure and volume is also constant
