A 4.00 g of solid copper metal react with 10.0 mL of concentrated nitric acid. Concentrated nitric acid is 12.0 M. The three products are copper(II) nitrate Cu(NO3)2, nitrogen monoxide (NO) and water. The NO gas collected, and it has a volume of 610 mL at STP conditions. Calculate the volume of NO gas should been formed theoretically. 3Cu (s) + 8HNO2 (aq) → 3Cu(NO3)2 (aq) + 2NO (g) + 4H20 (l)​
