Question

S + 6 HNO3 → H2SO4 + 6 NO2 + 2 H2O

In the above equation, how many grams of water can be made when 14.5 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

33.63 g H₂O

Step-by-step explanation:

The mole ratio of HNO₃ and H₂O is 6 : 2

Hence, 16.9 moles of HNO₃ will produce = 2/6×5.6 = 1.86 moles of H₂O

Also,

Mass = Moles × M.Mass

Mass = 1.86 mol × 18.02 g/mol

Mass = 33.63 g H₂O
