Suppose that you have a 60.0% solution of naoh. how many milliliters of water must be added to 30.0 ml of this solution to prepare a 35.0% solution of naoh? 15.5 ml21.4 ml51.4 ml72.8 mlcan’t determine the concentration because you need the density of the solution

Explanation:

1) Data:

a) C₁ = 60.0% (initial solution)

b) V₁ = 30.0 ml (initial solution)

c) C₂ = 0% (pure water)

d) V₂ = ? (pure water)

e) C₃ = 35.0% (final concentration)

2) Formula:

3) Solution:

a) Substitute values in the first formula:

b) Solve the equation (units are supressed just to manipulate the terms)
