How many moles of copper are present in a sample of tennantite with a mass of 2370 grams
A sample of tennantite with mass of 2370 g contains19.23 mol Cu.You must make the following conversions:Mass of tennantite → moles of tennantite → moles of CuStep 1. Calculate themoles of tennantite(Tn)Theidealchemical formula of Tn is Cu_12As_4S_13.Molar mass = (12×63.55 + 4×74.92 + 13×32.06) g/mol= (762.60 + 299.68 + 416.78) g/mol = 1479.06 g/molMoles of Tn = 2370 g Tn × (1 mol Tn/1479.06 g Tn) =1.60 24 mol TnStep 2. Calculate themoles of CuMoles of Cu = 1.6024 mol Tn × (12 mol Cu/1 mol Tn) =19.23 mol Cu...
