Glucose $($molar mass $=180\mathrm{.}16\frac{g}{m}ol)$ is a simple, soluble sugar. Glucose solutions are used to treat patients with low blood sugar.

Suppose you prepare a glucose solution using the described procedure.

Step $1$: Dissolve $276\mathrm{.}9g$ of glucose in enough water to make $500\mathrm{.}0mL$ of solution.

Step $2$: Transfer $18\mathrm{.}2mL$ of the solution to a new flask and add enough water to make $250\mathrm{.}0mL$ of dilute solution.

What is the concentration $($in $M)$ of the glucose solution at the end of the procedure?
