I think the The answer 1/1 or1/2! If it is not correct then ask some one else
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.
m < x = (m arc AD + m arc BC) / 2
= (140 + 90) / 2
= 230/2
= 115 degrees answer
