# How many molecules of glucose are in a xenopus oocyte if the total volume is 10 ul and the concentration of glucose is 10 mM?

##### 1 Answer

There are

#### Explanation:

The formula for **molarity** is:

#color(blue)(bar(ul(|color(white)(a/a) "Molarity" = "moles"/"litres"color(white)(a/a)|)))" "#

or

#color(blue)(bar(ul(|color(white)(a/a) M = n/Vcolor(white)(a/a)|)))" "#

In your problem,

∴

Now, we can use **Avogadro's number** to calculate the number of molecules.
