The molar mass for any element can be found under the symbol on the periodic table. For example, the molar mass of carbon is 12.01 g/mol. This means that in one mole of carbon there are 12.01 grams of carbon.Using Avogadro's Number to Calculate the Number of Molecules Say you have 2...
FAQ: How to Calculate the Number of Moles in a Gas Using the Ideal Gas Law? What is the definition of a mole in scientific terms? In chemistry, a mole is a unit of measurement used to express the amount of a substance. It is defined as the amount of a substance t...
To calculate the number of moles of a compound you have on hand, you divide the mass by the mass of one mole of the compound, which you can calculate from the periodic table.Using the Mole Fraction Equation The mole fraction formula is particularly easy to understand and use if you ...
3. Calculate Molarity Divide the number of moles of NaCl by the volume of the solution to get molarity. 0.21 moles ÷ 0.59 liters = 0.356 M. References Royal Society of Chemistry: Periodic Table ThoughtCo: What Is a Mole in Chemistry?
