To determine the new molarity of a solution after dilution, we can use the equation:

M1V1 = M2V2

Where:
M1 = initial molarity of the solution
V1 = initial volume of the solution
M2 = final molarity of the solution
V2 = final volume of the solution

In this case, the solution is diluted 10 times. This means that the volume of the solution is increased by a factor of 10, while the amount of solute (in this case, the centimeter solution) remains the same.


Since the question does not provide the initial molarity and volume, let's assume that the initial molarity of the centimeter solution is 1 M and the initial volume is 1 L (to simplify the calculations).

M1 = 1 M
V1 = 1 L


Since the solution is diluted 10 times, the final volume will be 10 times the initial volume:

V2 = 10 L


Now, we can use the equation M1V1 = M2V2 to calculate the final molarity:

(1 M)(1 L) = M2(10 L)
1 = 10M2
M2 = 1/10
M2 = 0.1 M

Therefore, the final molarity of the centimeter solution after being diluted 10 times is 0.1 M.
