  • Molarity is a very common way to measure concentration. It is defined as moles of solute per liter of solution.

    The molarity formula is:
    M = n / V
    M is molarity
    n is number of moles of solute
    V is volume of the solution in liters
    This equation may be rearranged to solve for any one of those three variables. The units of molarity are moles per liter, mol/L, or simply M, which is pronounced "molar."
    In this video, I also describe how to make a solution of a certain molarity.

    I just want to say thank you so much for reading everything out loud that you were showing on the screen. I am blind and this means so much to me. It helped me to follow along with exactly what you were doing. I’m actually a chemistry nerd, but I’ve always hated chemistry with numbers because it’s been difficult to visualize. Organic chemistry is more my style, but I needed this information to record a TikTok video, so thank you!

    NIce explanation! I`ve done them all correctly the first attempt (I accounted for 159.609g/mol as the molecular mass of CuSO4 as this is given when you look it up. However, the method was right and then I did it again with your 249.7g/mol). I got them all right:) - it`s simple, when you know-how.
