Question
A 23.0% by mass LiCl solution is prepared in water. What is the mole fraction of the water?
Answers

23% w/w LiCl means
23 g LiCl in (23g LiCl + 77 g H2O).
mols LiCl = 23/molar mass LiCl
mols H2O = 77/molar mass H2O
XH2O = mols H2O/total mols.
23 g LiCl in (23g LiCl + 77 g H2O).
mols LiCl = 23/molar mass LiCl
mols H2O = 77/molar mass H2O
XH2O = mols H2O/total mols.
