EXAM PROBLEM #1 Instructions:  Type your answers to the questions in the textbox below.  Label each answer (A, B, C). Show all work on your “work” page.  Identify which problem it is (#1) Situation: 385 grams of Cu and 975 grams of HNO3 are combined and they react according to this chemical equation: 3 Cu(s)  +  8 HNO3 (aq)  –>  4 H2O(l)  +  2 NO(g)  +  3 Cu(NO3)2 (aq) Molar masses for all substances: Cu = 63.55 g/mol   |   HNO3 = 63.02 g/mol  H2O = 18.02 g/mol   |   NO = 30.01 g/mol   |   Cu(NO3)2 = 187.57 g/mol Questions: How many grams of each of the following substances should be present at the end of the reaction? Cu HNO3 H2O
