STEP 1 State the given and needed quantities.

ANALYZE THE PROBLEM	Given	Need	Connect
ANALYZE THE PROBLEM	0.750 mole of Ag	grams of Ag	molar mass

STEP 2 Write a plan to convert moles to grams.

moles of Ag $\boxed{ Molar mass}$ → grams of Ag

STEP 3 Determine the molar mass and write conversion factors.

\boxed{\begin{array}{l} 1  mole  of  Ag = 107.9  g  of  Ag \\ \frac{107.9  g  Ag }{1  mole  Ag }         and         \frac{1  mole  Ag }{107.9  g  Ag } \end{array}}

STEP 4 Set up the problem to convert moles to grams.

0.750  \cancel{mole  Ag}    \times    \boxed{\frac{107.9  g  Ag}{1  \cancel{mole  Ag}} }  = 80.9  g  of  Ag
