If 35.8 grams of LiCl are dissolved in 184 grams of water, what is the concentration of the solution in percent by mass?

Answers

Mass of solute = 35 grams
Mass of solution = mass of nacl + mass of water = 35.8 + 184 = 219.8 grams


Concentration = mass of Nacl x 100/mass of solution.

= 35x100/219.8 = 15.92%.
