A lot of chemical reactions happen in a solution (it allows the chemicals to interact much more easily with each other when it is), so chemists define how much of the solute is in the solution by the term MOLARITY.


Molarity is a really convenient unit of concentration and it works like this. If I have 10 moles of solute in 10 liters of water, what’s the molarity? 10/10 = 1! So it’s a 1M solution. What if I have 20 moles in 10 liters? Then it’s a 2M solution. See how easy that is?

  1. Good afternoon, we have a question regarding the figure/number ‘8’ you wrote down after Sulfur (2:10 in video). We know about the 2 after Oxygen because oxygen is naturally found in the O2 form (correct me if I’m wrong please), but what if you don’t know that (as in our case with the sulfur); where can you find the figures that you need to start the equation balancing “process”? (you can refer us to a video if you’ve already answered the question)
    Thank you

  2. I’ll have Tonya connect with you right away!
