Unformatted text preview: Divide weight in grams by atomic weight Finding atoms: How many atoms of Potassium are present in 6.3mol of K 6.3 x atomic weight of K Molar mass: The sum of the atomic masses of each element in one mole of a compound expressed in grams. Units: g/mol Calculating Molar Mass: NH4NO3 (ammonium nitrate) (take atomic weight from each element and add them to obtain compound's weight) N: 14.008 H(4): 1.0080 N: 14.008 O(3): 16.00-Add these Chemical Equations: Shorthand representation of a chemical reaction. Atoms undergo reorganization. Bonds are broken and reformed Empirical Formula: Simplest formula of a compound which will show the relative whole number of each element in 1mol of a compound Molecular Formula: A formula that shows the actual number of each element present in 1mol of the compound ElementCarbonHydrogenOxygen Sheet1 Page 2 Percent48.648.1643.20 Atomic Weight12.011.00816.00...
