Answer:

The answer to your question is 0.6 M

Explanation:

Data

Volume = 250 ml

moles of sucrose = 0.15 mol

Molarity = ?

Formula

               [tex]Molarity = \frac{moles}{volume}[/tex]

Process

1.- Convert 250 ml to liters using proportions

                      1000 ml ----------------- 1 l

                        250 ml ----------------  x

                       x = (250 x 1 ) / 1000

                       x = 250 / 1000

                       x = 0.25 l

 2.- Substitute values in the formula

               [tex]Molarity = \frac{0.15}{0.25}[/tex]

3.- Simplification and result

                       Molarity = 0.6
