Learn how to calculate the percentage of a number, marks using simple steps and examples. Also, get the formulas to calculate the percentage difference between numbers here at BYJU’S.
Molarityis one of the most common units of concentration. It is used when the temperature of an experiment won't change. It's one of the easiest units to calculate. You get the mass of solute for the solution, mix the solute with a known volume of solvent, and divide mass by volume ...
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. To convert grams to moles, the molar mass ...

To find the percent yield the actual yield is divided by the theoretical yield the resulting answer is multiplied by 100. What is the formula for the theoretical yield? We calculate the theoretical yield by taking the given mass of the reactants and multiplying it by the molar mass ...
Molarity is measured in moles per liter (mol/L), whereas PPM is a measure of concentration (mass per unit volume) in which the denominator is, as the name of the unit implies, one million times that of the numerator. In standard units, then, 1 PPM translates to 1/1,000th of a gra...

Molarity (M) = (moles of solute) ÷ (liters of solution). To calculate the number of moles of a solute, you need two pieces of information, which you may have to infer from other data. The first is the chemical formula of the solute, and the second is the mass of the solute. Yo...
This quiz and corresponding worksheet will help you gauge your understanding of how to calculate molarity and molality concentration. Topics you'll need to know to pass the quiz include understanding the moles of a solute per liter of a solution as well as knowing when molality is usually ...
