Step-by-step explanation:
angle ABC is a parallel to angle DEF
after you subtract the answer is 2x-2y
We do as follows:
let x = amount of 45% solution
y = amount of 30% solution
overall balance => x + y = 450
acid balance => .45x + .30y = .40(450)
Solving simultaneously, we will have:
x = 300 mL
y = 150 mL
This is assuming that partial molar properties does not affect the volume greatly. Hope this answers the question. Have a nice day.
