Answer:
The molarity of the final solution is 1 M.
Explanation:
A simple equation to use is M1V1=M2V2.
M=molarity
V=volume
M1V1 are the initial conditions, while M2V2 are the final conditions. Initially, the problem tells us that the solution is 2 M with an initial volume of 1 L. It also gives the final volume, but not the final molarity, which is what we are trying to solve for. Using the equation, plug in the given conditions:
M1V1=M2V2
(2 M)(1 L) = (M2)(2 L)
Solve for M2, the final molarity.
M2=(2 M)(1 L)/(2 L)
M2= 1 M
