Explanation:To find the number of moles of solute in a volume of a solution, we need to multiply volume by concentration. BUT we also need to check that the units are the same. Molarity (M) is moles per liter, so we need to convert 250mL to L.

250mL=0.250L

Now we can multiply the concentration by volume.

0.4M*0.250L
