While working in a metal processing facility, Letlen had accidentally mixed two metal vats together creating an alloy. One vat was labeled for cadmium, while the other was not. It can be assumed that these are of pure metal composition. To identify this metal, Letlen took 1.000 g of the homogenous alloy sample composed of cadmium and the unknown metal, dissolved, and diluted it to exactly 100.0 mL in a volumetric flask. A 20.00-mL aliquot was taken and titrated this using 22.82 mL of 0.05000 M EDTA. In a second 20.00-mL aliquot, the Cd was masked through the addition of HCN/NaCN buffer. The titration of the unknown metal in the aliquot required 15.13 mL of EDTA. MW: Cd (112.411 g/mol) a. Calculate the moles of Cd and the moles of unknown metal in the 20.00-mL aliquot. b. Calculate the moles of Cd and the moles of unknown metal in the sample.

Question
While working in a metal processing facility, Letlen had accidentally mixed two metal vats
together creating an alloy. One vat was labeled for cadmium, while the other was not. It can
be assumed that these are of pure metal composition.
To identify this metal, Letlen took 1.000 g of the homogenous alloy sample composed of
cadmium and the unknown metal, dissolved, and diluted it to exactly 100.0 mL in a
volumetric flask. A 20.00-mL aliquot was taken and titrated this using 22.82 mL of 0.05000
M EDTA.
In a second 20.00-mL aliquot, the Cd was masked through the addition of HCN/NaCN buffer.
The titration of the unknown metal in the aliquot required 15.13 mL of EDTA.
MW: Cd (112.411 g/mol)
a. Calculate the moles of Cd and the moles of unknown metal in the 20.00-mL aliquot.
b. Calculate the moles of Cd and the moles of unknown metal in the sample.
