Final answer:
To prepare a 0.50M solution, you can use the formula M1V1 = M2V2, where M1 and V1 are the initial molarity and volume and M2 and V2 are the desired molarity and volume. The volume of the initial solution needed depends on its molarity.
Step-by-step explanation:
To prepare a 0.50M solution, you need to use the formula:
M1V1 = M2V2
Where M1 is the initial molarity, V1 is the initial volume, M2 is the desired molarity, and V2 is the desired volume.
Given that the desired molarity is 0.50M and the desired volume is 1.00L, we can rearrange the formula to solve for V1:
V1 = (M2 * V2) / M1
Substituting the given values, we have:
V1 = (0.50M * 1.00L) / M1
So, the volume of the initial solution needed to prepare the desired solution depends on the molarity of the initial solution.
