A 3.0 cm piece of copper wire (density 8.96 g/cm3) with a diameter of 4.0 mm is reacted with excess nitric
acid. Calculate the mass of nitrogen monoxide gas released. Show and cancel units throughout your
answer.
3 Cu(s) + 8 HNO3(aq) → 3 Cu(NO3)2(aq) + 2 NO(g) + 4 H2O(l)
Homework Answers
Dear student,
First you need to find the volume of copper by pi*r^2*l formula from that we can find mass of copper and then as given in equation excess of nitric acid with no of moles producing NO by Cu need to be seen and calculated.Detailed work is provided below for your clear understanding.
If something is not clear or need further clarification,Please feel free to comment here for further discussion.

Consider a straight piece of copper wire of length 8 m and diameter 8 mm that carries a current I = 4.5 A. There is a magnetic field of magnitude B directed perpendicular to the wire, and the magnetic force on the wire is just strong enough to “levitate” the wire (i.e., the magnetic force on the wire is equal to its weight). Find B. Hint: The density of copper is 9000 kg/m3 .
