Given a solution of ammonia that is 14.8 M, how many milliliters
of this solution should dilute to make 100.0 mL of 0.250M ammonia?
Provide an answer correct to 2 significant figures. For example, if
you calculate that the correct answer is 12 milliliters, simply
type 12 in the box. Do not answer this question using scientific
notation. Do not include units in your answer.
(hint: this is a dilution question. How do you know? What equation
do you use to calculate dilutions? It has four variables. If you're
given 3 of the 4, can you find the 4th?)
