Question

30mL solution of a 1:6 syrup solution. You have on hand a 50% syrup solution and a 1:200 soda solution. How many mL of each do you need to create this final solution?

Answer 1

Answer:

5.73mL of 50%

Explanation:

Let's say the amount of 50% solution to be used is, y

Therefore 37-y = the amount of 1/200 solution used

The set up will then be,

0.5y +0.05(37-y) = 1/6(30)

0.5y + 1.85 -0.05y = 5

0.55y = 3.15

y= 5.73mL of 50%
