Question

Setup a problem to find the theoretical yield: A 15 mL sample contains 1.4 g Copper(II) nitrate. Use Reaction 1 to calculate the amount of copper wire needed to make this solution. Hint: Begin writing the balanced molecular Reaction that represents the chemical reaction. Identify the compounds that are involved in the chemical reaction and set up the stoichiometric calculation. Recall from lecture that you can convert from grams of substance A to grams of substance B using the molar masses of both and the coefficients in the balanced equation. g A → mol A → mol B →g B Show your calculations in the space provided here. Reaction 1 Cut4HNO₃ Cu(NO3)2 + 2NO₂+ 2H₂O

Answer 1

The given reaction is: Cu + 4HNO3 Cu(NO3 +2.002+2th It tells that, lequivalent of Cu(coppes) com get us lequivalent of Cu(NO3)(Copper nitrate). Thus, moles of Cu used moles of Cu(NO3), produced. Griven andent of Cu (403) > ling Mol.cof. of Cu (03) 187.56 g/mol. .: moles of Cu(NO3)2 2 1 may and lig og mod : moloof of Cu = 63.546 g/mol .: Grams of Cuo- wire used 1 19.56 x 63.5469 20.ufug
