Question

How many moles of water will form if the reaction has 9 moles of Cu?
how many moles of NO will form if the reaction has 9 moles of Cu?
3Cu+8HNO3->3Cu(NO3)2+4H2O+2NO

Answer 1

12 moles of H20
6 moles of NO

3 moles of Cu=4 moles of H2O=2 moles NO

9 mol of Cu*( 4 mol of H20/3 mol of Cu) = 12 moles of H2O

9 mol of Cu*( 2 mol of NO/3 mol of Cu) = 6 moles of NO
