Answer:
11.4 moles
Explanation:
Your chemical equation for the reaction of zinc and nitric acid will be
Zn + 4 HNO₃ --> Zn(NO₃)₂ + 2 NO₂ + 2 H₂O
To solve the problem, you need to use stoichiometry. For every 1 mole of zinc, you will need 4 moles of nitric acid. Divide 45.60 by 4. Your answer should be 11.4 moles.
