Question

W how much ulader should be added to 150 g salt ato
obtain 15% of salt solution​

Answer 1

Answer:

Concentration of solution = 15%

Mass of solute = 15g

Mass of solvent = 15 + x

Concentration of solution = (Mass of solute /Mass of solution) *100

15= (15/15+x)*100

15 + x = (15/15)*100

x =100-15

x = 85g
