Final answer:
To determine how much 1.50M KBr can be made from 15.6 mL of concentrated KBr with a molarity of 9.65 M, we can use the equation: M1V1 = M2V2. The final volume of the solution is 100.1 mL.
Step-by-step explanation:
To determine how much 1.50M KBr can be made from 15.6 mL of concentrated KBr with a molarity of 9.65 M, we can use the equation:
M1V1 = M2V2
where M1 and V1 are the initial molarity and volume, and M2 and V2 are the final molarity and volume.
In this case, M1 = 9.65 M and V1 = 15.6 mL = 0.0156 L.
We want to find V2 when M2 = 1.50 M.
Using the equation, we have:
(9.65 M)(0.0156 L) = (1.50 M)(V2)
Solving for V2:
V2 = (9.65 M)(0.0156 L) / 1.50 M = 0.1001 L or 100.1 mL
