How do I find how many moles are in 0.204 M potassium permanganate?
What does the 'M' in "0.204 M" stand for?
Take a guess. Any guess is right. You must name a volume before you know how many moles are in it.
M= molarity
I think my volume it 22.3mL
moles = M x L
To find the number of moles in a solution, you can use the equation:
moles = concentration (M) x volume (L)
In this case, you have the concentration of potassium permanganate (KMnO4) as 0.204 M. However, to calculate the number of moles, you also need the volume of the solution.
If you have the volume of the solution, simply multiply it by the concentration to find the number of moles. For example, if you have a 1 liter solution:
moles = 0.204 M x 1 L = 0.204 moles KMnO4
If you don't have the volume of the solution, you won't be able to calculate the number of moles exactly. However, you can estimate the number of moles by assuming a certain volume. Just make sure to specify the volume you are assuming when reporting the result.
