Then, find the molar mass of the following compounds:

1)    Ca(OH)₂

2)         Na₃PO₄

3)         AgF

4)         Fe₃(PO₄)₂

5)         Zn(C₂H₃O₂)₂

Use the chart we created in class (a similar one can be found on page 84 of your textbook) to

determine the mass in grams of each of the following:

a.      1.35 mol Fe

b.      24.5 mol O

c.      0.876 mol Ca

Calculate the number of moles of each compound:

a.     21.5 g CaCO₃

b.     1.56 g NH₃

c.    16.8 g Sr(NO₃)₂
