Question 889035
Nearly ANY of the tutors who you asked should be able to help you with this question.


The 25 grams of salt in the 500 ml.  total volume is not too concentrated, so you can probably ignore density.  For m/v, meaning "MASS PER VOLUME", the concentration is {{{(25/500)(grams/ml)}}}, or {{{(25/500)*100}}}%, as mass per volume.


5% LiCl.


Just be aware that this concentration may be significant enough to require accounting for density.  Consult a handbook for that.
