A student (Becky) is helping a friend (Taylor) solve a stoichiometry problem. Taylor needs to know how many liters of nitrogen monoxide (NO) gas are created at STP when 150 g of solid copper reacts with excess nitric acid. 3Cu(s) + 8HNO3 (aq) 3Cu(NO3), (aq) + 4H20(1) + 2NO(g) Taylor knows they should put 150 g Cu down first, and they also know they need to convert from grams to something else. Becky provides a clue to Taylor: they will need 3 conversion factors (which are empty, below). What does Taylor need in order to complete the third conversion factor? 150 g Cu 1 Coefficients from the balanced equation (molar ratio) O The molar mass of nitrogen monoxide O The molar mass of copper Avogadro's number The STP volume of gas (22.4 L/mol)
