You Can Dissolve a Penny Using Nitric Acid, HNO₃ $\rarr$ Cu(NO₃)₂(aq)+ 2 NO₂(g)+ 2 H₂O(l)is Used to Dissolve Copper Metal

Multiple Choice

You can dissolve a penny using nitric acid, HNO₃. The reaction
Cu(s) + 4 HNO₃(aq) $\rarr$ Cu(NO₃) ₂(aq) + 2 NO₂(g) + 2 H₂O(l) is used to dissolve copper metal. If there is 1.000 g of copper to be dissolved, and instructions say to use four times as much acid as the required amount, how many mL (to the nearest mL) of 15.0 M nitric acid would be required to dissolve the copper? Hint: Don't forget the coefficients in the balanced reaction above when performing your calculations with nitric acid.

A) 4 mL
B) 5 mL
C) 10 mL
D) 17 mL
E) 25 mL
