1.) S   + 6 HNO3 → H2SO4 + 6 NO2 + 2 H2O

In the above equation, how many grams of water can be made when 17.7 moles of HNO3 are consumed?

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 Sulfur 32 Oxygen 16

2.) 3 Cu + 8HNO3 → 3 Cu(NO3)2   + 2 NO + 4 H2O

In the above equation, how many grams of water can be made when 18 moles of HNO3 are consumed?

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
