Answer:
13 moles of HNO3 can produce 13/6 moles of H2SO4.
Step-by-step explanation:
Looking at the balanced chemical equation:
S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O
We can see that for every 1 mole of sulfur (S) and 6 moles of nitric acid (HNO3) that react, we get 1 mole of sulfuric acid (H2SO4) as a product. Therefore, we can use the mole ratio between HNO3 and H2SO4 to determine how many moles of H2SO4 can be produced from 13 moles of HNO3.
From the equation, we can see that the mole ratio of HNO3 to H2SO4 is 6:1. This means that for every 6 moles of HNO3 that react, we get 1 mole of H2SO4.
To find out how many moles of H2SO4 can be produced from 13 moles of HNO3, we can set up a proportion:
6 moles of HNO3 : 1 mole of H2SO4 = 13 moles of HNO3 : x moles of H2SO4
Simplifying the proportion:
6 : 1 = 13 : x
6x = 13
x = 13/6
