Add the two expressions for NaI used and set the sum equal to the total moles of NaI:
(0.00425944 z) (0.103873 0.00440142 z) = 0.102
Solve for z algebraically:
z = 13.2 g AgI
Let z be the mass of AgI (in grams) to be found.
Then 23.6-z is the mass of HgI2.
Ag{ } NaI AgI Na{ }
z / (234.77267 g AgI/mol) x (1 mol NaI / 1 mol AgI) = (0.00425944 z) mol NaI used for the AgI
Hg{2 } 2 NaI HgI2 2 Na{ }
(23.6-z) / (454.3989 g HgI2/mol) x (2 mol NaI / 1 mol Hgi2) = (0.103873 0.00440142 z) mol NaI used for the HgI2
