HINT: If there is no coefficient AND no subscript right after the chemical symbol, there is 1 atom of that element. Note: ALL examples need to have their subscripts circled and coefficients boxed. Example 1: O2. 2 O’s (oxygen) O=2. Example 2: CaCl2. 1 Ca(calcium) Ca=1 . 2 Cl’s(chlorine) Cl=2. Example 3: 3CaCl2. 3 Ca’s(calcium)

Molar mass tells us the mass (“weight”) of 1 mol of an atom or compound. In each case . we simply calculate the sum of the “weights” of the atoms in the formula to determine the weight of a mole. These weights can be found on the periodic table. EXAMPLE: Calculate the molar mass (gram molec ular weight) of a mole of iodine, I2.

First you need to find the atomic mass of your element and round it to the nearest hundredths place. The atomic mass is :_____ Atomic mass gets the unit a.m.u. for atomic mass unit. Now, if you were to have 6.02 x 1023 atoms of any element, you would have a mass in grams equal to the atomic mass and the a.m.u. unit could be changed to grams.

Dashing to the lab you carefully mass this material. Igor tells you the balance reads exactly 18.265 grams. Excitedly Igor pours the sample into the ACME atom counter and turns it on. The numbers rush by in a blur. The only sound to be heard is the wind howling outside the lab windows. Suddenly the dials on the atom counter come to a halt.
