Molarity & Stoichiometry | Definition, Formula & Calculation from Chapter 9 / Lesson 4 87K Learn how to find the molarity of a solution or the moles of gas in a given volume using stoichiometry. See examples of calculating moles from molarity. Related...
The pH scale ranges from 0 to 14 under usual conditions and measures the acidity of an aqueous solution. This is derived from the molarity of protons (hydrogen ions, or H+) in the solution. To find pH for a given molarity, you need to know how to work wi
Answer to: How do you find the molarity (M) of NaOH in this reaction with 0.2079 g of H2C2O4 2H2O: 2NaOH(aq) + H2C2O4 H2O arrow Na2C2O4(aq) + 2H2O...

To find the molarity, you can divide the number of moles by the volume of the solute (in liters): \(\mathrm{\dfrac{0.36mol\enspace NaCl}{0.1L}=3.6M\enspace NaCl}\) This means that a 21% w/v solution of NaCl is the same as a 3.6 solution of NaCl. In this way, you can co...
