questions but the questions are related to each other so I must post them together. Please answer only if you will answer all. Thank you for your time. Molecular Weights: -Cadmium 112.411g/mol Two metal vats was unintentionally combined producing an alloy. The first vat was unlabeled, the second one was labeled Cadmium. 1.0g of the homogenous alloy was dissolved and diluted to 100mL in a volumetric flask. A 20mL aliquot was taken from this and titrated using 22.82mL pf 0.05M EDTA. In another 20mL aliquot the cadmium was m@sked through the addition of HCN/NaCN buffer. 15.130mL of EDTA was need to titrate the unknown metal. a. Give the moles of cadmium and the unknown metal present in the 20mL aliquot. b. Give the moles of cadmium and the unknown metal present in the sample. c. Give the mass (g) of cadmium and the mass of the unknown metal in the sample. d. Give the molecular weight (g/mol) of the unknown metal. e. Give the identity if the unknown metal.
