Question

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

In the above equation how many moles of water can be made when 66 moles of HNO3 are consumed?

Answer 1

792 moles.

Step-by-step explanation:

When 66 moles of HNO3 are consumed, 6 x 66 = 396 moles of NO2 are produced.

Since the equation shows a 1:2 mole ratio between HNO3 and H2O, the number of moles of H2O produced is 2 x 396 = 792 moles.
