Question

How much water should be added to 10 mL of 14% alcohol solution to reduce the concentration to 5%?

We should add___mL.

Answer 1

Answer:

X = 2 mL

Step-by-step explanation:

Let's do it  

 

X = the amount of water added to the solution (in mL)

 

.06(10) = .05(10 + X)

.6 = .5 + .05X

.1 = .05X

2 = X

 

X = 2 mL
