Pressurized metаl gаs cylinders аre generally used tо stоre cоmmonly used gases in the laboratory. Attimes 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(l)If 5.0 g of copper metal was added to an aqueous solution containing 2.5 moles of HNO3, how manymoles of NO(g) would be produced, assuming a 100% yield?A) 0.042 mole NOB) 0.052 mole NOC) 0.062 mole NOD) 0.72 mole NOE) None of the above
