ANSWER THIS QUESTION WITH STEPS...​

Answer 1

Mass of solute = x

Concentration = 40%

Mass of solution = 600 g

— x/600 g * 100 = 40 = x/6 g

— 40*6 g = 240 g

Mass of solute = 240 g

Answer 2

If concentration by mass of 600 g NaCl solution is 40 %, find amount of solute by mass in this solution.

Solution:

100 g solution includes 40 g solute

600 g solution includes X g solute
