-6/3 division sign 2/-9
To solve: multiply by reciprocal inverse
-6/3 x -9/2= 54/6 or 9
Answer:
135 degrees
Step-by-step explanation:
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.
