Answer:

The answer to your question is 0.033 M

Explanation:

Data

moles of sucrose = 0.01

Molarity = ?

Volume = 300 ml

Formula

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

Process

1.- Convert volume to liters using proportions

                  1000 ml --------------------- 1 liter

                    300 ml -------------------   x

                     x = (300 x 1) / 1000

                     x = 300 / 1000

                     x = 0.3 liters

2.- Substitute values in the formula

               [tex]Molarity = \frac{0.01}{0.3}[/tex]

3.- Simplification and result

                      Molarity = 0.033
