Question

3 Cu + 8HNO3 --> 3 Cu(NO3)2   + 2 NO + 4 H2O

In the above equation how many grams of water can be made when 6 grams of HNO3 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

Standard stoichiometry / dimensional analysis: (6 g HNO₃) * (1 mole HNO₃ / 63 g HNO₃) * (4 mole H₂O / 8 mole HNO₃) * (18 g H₂O / 1 mole H₂O) + 0.9 g H₂O.
