You have stock solution of 16.0 M NH3 how many millilitres of this solution should you dilute to make 1200ml of 0.220
16.5 mL
The relationship between the molarity and volume of a stock and diluted solution is M1V1 = M2V2 where M1 and V1 are the molarity and volume of the stock solution and M2 and V2 are the molarity and volume of the diluted solution. We are described the molarity of the stock solution as well as the molarity and volume of the desired solution so we can solve for the volume of the stock solution required.
M1V1 = M2V2
(16.0 M)(V1) = (0.220 M)(1200 mL)
V1 = 16.5 mL
