S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O In the above equation how many moles of water can be made when 135.8 grams of HNO3 are consumed?

Question

S   +   6 HNO₃  -->  H₂SO₄  +  6 NO₂  +   2 H₂O

In the above equation how many moles of water can be made when 135.8 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
Sulfur	32
Oxygen	16

Answer 1

Hi Nathan W.!

This is a rather straightforward application of stoichiometry. We simply convert our mass of nitric acid into moles, so we can use the stoichiometric ratios provided in the balanced equation to our advantage:

(135.8g HNO₃₎(1 mol HNO3/63g HNO₃)(2 mol H₂O/6 mol HNO₃)

mass = 0.7g H₂O

Hope this helps!

Cheers
