Tutors, please sign in to answer this question.

It appears to me all you need to focus on is that if the solution is 100 g this will be 5% LiCl, or 5.00 g LiCl, and 95% water, or 95.0 g water.

In summary, in a 100 g 5% aqueous solution of LiCl:

(i) solution, 100 g.

(ii) LiCl, 5.00 g.

(iii) water, 95.0 g.

Taking any one of these divided by another will yield a unit factor.

All but (3) are contructed correctly. The "95.0 g solution" is the problem.

Hope this helps.
