The atomic mass of each element is added together to find the number of grams in one mole. This is called the molar mass and can be used to convert from mass to moles. For example, to find the molar mass of H2O, find the mass of two hydrogen atoms and one oxygen atom and add ...
What is the mass of 4 atom(s) of copper in grams? If the atomic mass of an element is x, what is the mass in grams of 6.02 X 10^{23} atoms of the element? What is the mass in kilograms of a single atom of carbon? What is the average mass of a single silicon atom in grams?
The number of grams in the molar mass of an element is the same as the atomic mass. Translating atomic masses into molar masses, you can construct conversion factors that convert between the mass of an element and the number of moles of the element. For example, the atomic mass of the...
Example: Converting between mass and moles Avogadro, Gay-Lussac, Dalton, and the history of the mole concept Avogadro’s number combines with the mole Atomic weight, molecular weight, and molar mass Example: Calculating sulfur’s atomic weight ...
SOLUTION Analyze We are given the number of moles and the name of a substance and asked to calculate the number of grams in the substance. Plan To convert moles to grams, we need the molar mass, which we can calculate using the chemical formula and atomic weights. Solve Because the calciu...

The reactants must be weighed out in the correct amounts based on the number of moles required. Then the product of the reaction is weighed to calculate the yield of the reaction in grams, which can be converted to moles. Each of these steps uses the molar mass as a conversion factor...
(mol/L) 6.0 M HCl 6.0 moles of HCl per liter of solution. 9.0 M HCl 9.0 moles of HCl per liter of solution. Chapter 5 Molarity can be used as a conversion factor. The definition of molarity contains 3 quantities: Molarity = moles of solute volume of solution in liters If you know...
