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 aq 4H O 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 first conversion factor Below is what Devin has so far 32 2 g Cu X O The molar mass of nitrogen monoxide O The STP volume of gas 22 4 L mol Avogadro s number O The molar mass of copper O Coefficients from the balanced equation molar ratio
