Solution

To solve this problem, we can use the formula M1V1 = M2V2, where M1 is the initial molarity, V1 is the initial volume, M2 is the final molarity, and V2 is the final volume.

Given: M1 = 2.84 M V1 = 52.9 mL M2 = 2.00 M

We need to find V2.

Substituting the given values into the formula, we get:

2.84 M * 52.9 mL = 2.00 M * V2

Solving for V2, we get:

V2 = (2.84 M * 52.9 mL) / 2.00 M

V2 = 75.246 mL

Rounding to three significant digits, the final volume V2 is 75.2 mL.
