To find molar mass: look for each element on the table and find their atomic masses. Then add each atomic mass to find the molar mass. If there is a subscript then that means that there is 3 of that number. For atomic mass round to the nearest hundredths
FeCl3= 162.2
Fe2(SO4)3= 354.88
PbO=223.2
PbO2 = 239.2
Pb3O4=685.6
