A student (Sam) is helping a friend (Devin) solve a stoichiometry problem. Devin needs to know how many liters of nitrogen monoxide (NO) gas are created at STP when 32.2 g of solid copper reacts with excess nitric acid. 3Cu(s) + 8HNO3 (aq) 3Cu(NO3)2 (ag) + 4H2O(1) + 2NO(g) Devin knows they should put 32.2 g Cu down first, and they also know they need to convert from grams to something else. Sam provides a clue to Devin: they will need 3 conversion factors (which are empty, below). What does Devin need in order to complete the second conversion factor? 32.2 g Cu 1 O Coefficients from the balanced equation (molar ratio) The STP volume of gas (22.4 L/mol) O The molar mass of nitrogen monoxide O Avogadro's number The molar mass of copper
