Question

Calculate the mass of NO that can be produced by the reaction of 29.5 g HNO₃ according to the following balanced equation.

8 HNO₃(aq) + 3 Cu(s)  2 NO(g) + 3 Cu(NO₃)₂(aq) + 4 H₂O(l)

Answer 1

8 HNO₃(aq) + 3 Cu(s)  2 NO(g) + 3 Cu(NO₃)₂(aq) + 4 H₂O(l)

Use the stoichiometry of the equation and dimensional analysis:

29.5 g HNO₃ x 1 mol HNO₃ / 63 g x 2 mol NO / 8 mol HNO₃ x 30 g NO / mol = 3.51 g NO
