Share Flipboard Email. Anne Marie Helmenstine, Ph. To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms. For example, the molar mass of NaCl can be calculated for finding the atomic mass of sodium The molar mass of NaCl is Molar Mass Calculations — YouTube : This video shows how to calculate the molar mass for several compounds using their chemical formulas.

Convert between the mass and the number of moles, and the number of atoms, in a given sample of compound. Chemists generally use the mole as the unit for the number of atoms or molecules of a material. One mole abbreviated mol is equal to 6. The molar mass of any element can be determined by finding the atomic mass of the element on the periodic table. For example, if the atomic mass of sulfer S is Converting between mass, moles, and particles : This flowchart illustrates the relationships between mass, moles, and particles.

These relationships can be used to convert between units. What is the molar mass of NaOH? If the equation is arranged correctly, the mass units g cancel out and leave moles as the unit. According to the periodic table, the atomic mass of nickel Ni is The answer is 1. We assume you are converting between mole and molecule. You can view more details on each measurement unit: moles or molecule The SI base unit for amount of substance is the mole.

In this case, the mole is used as a common unit that can be applied to a ratio as shown below:. To think about what a mole means, one should relate it to quantities such as dozen or pair.

Just as a pair can mean two shoes, two books, two pencils, two people, or two of anything else, a mole means 6. Using the following relation:. It is quite difficult to visualize a mole of something because Avogadro's constant is extremely large. For instance, consider the size of one single grain of wheat. If all the people who have existed in Earth's history did nothing but count individual wheat grains for their entire lives, the total number of wheat grains counted would still be much less than Avogadro's constant; the number of wheat grains produced throughout history does not even approach Avogadro's Number.

Similarly, if the moles of a substance are known, the number grams in the substance can be determined. One simply needs to follow the same method but in the opposite direction. Multiply moles of Ca by the conversion factor molar mass of calcium The total number of atoms in a substance can also be determined by using the relationship between grams, moles, and atoms.

Then the number of moles of the substance must be converted to atoms.
