Question

Pressurized metal gas cylinders are generally used to store commonly used gases in the laboratory. At times it can be easier to chemically prepare occasionally used gases. For example, nitrogen monoxide, NO(g), can be prepared in the lab using the following chemical reaction: 3Cu(s) + 8HNO3(aq) → 2NO(g) + 3Cu(NO3)2(aq) + 4H₂O(1) If 5.0 g of copper metal was added to an aqueous solution containing 2.5 moles of HNO3, how many moles of NO(g) would be produced, assuming a 100% yield?
0.042 mole NO
0.052 mole NO
0.062 mole NO
