2.  Mole (mol) can be defined as the number equal to the number of carbon atoms in 12.01 grams of carbon (in an chemical equation it is the coefficients that tell how many moles of each compound there are)  Avogadro’s number- one mole of something (anything) consists of 6.022 x 10 23 units (atoms, molecules, particles, etc…) of that substance  1 mol = 6.022 x 10 23 units  Molar mass- is obtained by summing the masses of the component atoms

3.  1 mol of Ag= 107.9 amu or g/mol  1 mol of Ag= 6.022 x10 23 atoms  1 mol of Pb= 207.2 amu or g/mol  1 mol of Pb= 6.022 x 10 23 atoms  Molar mass of CH 4 = 16 g (1 C and 4 H)  Molar mass of CaCO 3 = 100 g (1 Ca, 1 C and 3 O)  Molar mass of C 10 H 6 O 3 = 174.1 g (10 C, 6 H, and 3 O)
