The solution is made up of a A, B, and C in 4:3:1 proportions. How much of each is present if the whole solution has a volume of 350 mL?

Answer 1

350/8 = 43.75

A = 4(43.75) = 175 mL

B= 3(43.75) = 131.25 mL

C = 43.75 mL

Answer 2

4 parts + 3 parts + 1 part = 8 parts total

How much is each part?

350 ml / 8 parts = 43.75 ml per part

4 parts A = 4 x 43.75 ml = 175 ml A

3 parts B = 3 x 43.75 ml = 131.25 ml B

1 part C = 1 x 43.75 ml = 43.75 ml C

Total volume................. = 350.00 mls
