HCF or Highest Common Factor can be found by using the Prime Factorisation method and Division Method. Learn to find HCF by shortcut method or formula with examples at BYJU'S.
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
Mode is the value which occurs the maximum number of times in a given data set. For example, in {2,2,4,5,6}, mode is 2. Mode formula. Find a simple and easy method to find mode with examples at BYJU’S.
Molarity is the number of moles per liter of solution. The equation we use for molarity is: {eq}\begin{array}{*{20}c} {M = \dfrac{{\begin{array}{*{20}c} {Moles \ Solute} \\ \end{array}}}{{\begin{array}{*{20}c} {Liter \ of solution} \\ \end{array}}} \\ \end{arra...
Determine the molarity of the hydroxide in your sample. This is accomplished by dividing the calculated equivalent in the previous step by the volume of your water sample. Step 6 Take the negative log base 10 of the molarity of hydroxide to get the total alkalinity of the sample. For example...
Find the mole ratios for the following balanced chemical equation: 2 SO2 + O2 --> 2 SO3. How do you calculate percentage yield of a chemical reaction? How do you do stoichiometry with molarity? In the following stoichiometry problem, How does 4.5 moles of H2O cancel out 2 moles of H...

Calculate the molarityof a solution prepared by dissolving 23.7 grams of KMnO4into enough water to make 750 mL of solution. This example has neither the moles nor liters needed tofind molarity, so you must find the number ofmolesof thesolutefirst. ...
Depending on how the concentration is stated, there are different ways to convert to molarity (M). For example if the concentration is given as grams / ml (g/ml), we would first convert the g to moles (using molar mass) and then convert ml to liters (L) by dividing my ...
You need to find out the mass of the solvent.Ultimately, I need to determine the Molarity of the solution but I need the mass of solvent(the water in the HCl solution) to determine the mass of solute which will allow me to determine the moles of solute necessary for the Molarity.10g...
