.80x+.30y=400*.62
.80x+.30y=248
This is equation one.
x+y=400
x=400-y
This is the second equation.
.80(400-y)+.30y=248
320-.80y+.30y=248
-.50y=-72
Y=144
X=256
CHECK
.80(256)+.30(144)=400(.62)
204.8+43.2=248
248=248

150 mL x 40.0 g LiNO3/100 mL solution = 60.g of solute
Because some industrial diamonds are not naturally-occurring diamonds, a chemist is required to formulate the recipe for materials necessary to fabricate man-made diamonds.
400 mls would require 40g of glucose for a 10% solution and thus 20g for a 5% solution.
