Question
A graduated cylinder was used to transfer 201 mL of a 0.478 M solution of KCl to a beaker which was subsequently diluted to a final volume of 1.092 L. What is the final molarity of the KCl in the beaker after the solution is thoroughly mixed?

The calculation is done this way.
0.478M x (201 mL/1092 mL) = ?
I don't know if this is a play on significant figures; I ask because measuring 201 mL with a graduated cylinder is not very accurate. I expect the amount actually transferred was between 199 and 201 and perhaps not even that close.
