S + 6 HNO3 → H2SO4 + 6 NO2 + 2 H2O In the above equation, how many grams of water can be made when 19.1 moles of HNO3 are consumed?

Question

S   +   6 HNO₃ →  H₂SO₄  +  6 NO₂  +   2 H₂O

In the above equation, how many grams of water can be made when 19.1 moles 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
Sulfur	32
Oxygen	16

Answer 1

You get 114.6 grams of water.

19.1 moles HNO3 x (2 moles H2O/ 6 moles HNO3) = 6.367 moles of H2O.

6.367 moles H2O x (18.0 grams H2O / 1 mole H2O) = 114.6 grams of H2O.
