Hi,
from the reaction of 3 moles of fluorine (F₂) with 5 moles of hydrogen (H₂), 5.82 moles of HF
H₂ + F₂ -> 2HF

the stechimetric ratio is 1:1, and the limiting element is F₂.
The yield should be 58% 

[AWK]

How many moles of HF you can obtain from 3 moles of F₂?

[magnus]

5.82 moles

[AWK]

This is the real yield. I asked for the theoretical one. So the yield is ...?

[AWK]

Sometimes we ask for the yield in reference to the specified reagent. But this should be clearly stated.

?
5H₂ + 3F₂ -> ?HF

[magnus]

3 moles of H₂ react with 3 moles of F₂ -> 6 moles HF according to the stoichiometric ratio

H₂ + F₂ -> 2HF

[AWK]

This is a theoretical yield.

[magnus]

5.82/6 * 100= 97%

[AWK]

Solved.
