Determine the number of atoms in the following chemical formulas. Make sure you list the elements, how many atoms of each element, and how many total atoms. Numbers 1 and 6 have been completed as examples.

8NaCl = 8+8=16 (To find the total number of atoms add the total number of atoms)
Na=1x8=8 (remember to multiply the subscript by the coefficient)
Cl=1x8=8
