Homework Statement
Use the unbalanced equation NaN3 → Na + N2 to answer the following question(s).
The % yield of an experiment in which two moles NaN3 was used and 21 g nitrogen was isolated is ________.
Homework Equations
percent yield=({actual yield}/{theoretical yield})100%
The Attempt at a Solution
First, I balanced:
2NaN3 → 2Na + 3N2
And I convert my known mass to moles:
[tex]21g of N_{2}* \frac{3 mol N_{2}}{28 g N_{2}}=2.25 mol N_{2}[/tex]
...and that's where I'm stuck. I'm preparing for a comprehensive final exam, and it seems I have forgotten this piece from the beginning of the semester.
Edit:The LATEX ref is failing for some reason. it is 21g(3mol/28g)=2.25 mol
