2 NH3 + 3 CuO --> 3 Cu + N2 + 3 H2O

Question

2 NH₃  +  3 CuO  --> 3 Cu  +  N₂  +   3 H₂O

In the above equation how many moles of N₂ can be made when 187.7 grams of CuO are consumed?

Round your answer to the nearest tenth. If you answer is a whole number like 4, report the answer as 4.0

Use the following molar masses. If you do not use these masses, the computer will mark your answer incorrect.:

Element	Molar Mass
Hydrogen	1
Nitrogen	14
Copper	63.5
Oxygen	16

Answer 1

2 NH₃  +  3 CuO  --> 3 Cu  +  N₂  +   3 H₂O

187.8 g CuO x 1 mol CuO/molar mass CuO x 1 mol N2 / 3 mol CuO = mols N2
