can you write an equation for the reaction and balance it?

okay good stuff, now covert the grams of NH3 to moles
anonymous
  • anonymous
ok so find the molar mass?
aaronq
  • aaronq
well yeah, then find the moles moles=mass/molar mass

.653

okay so you have this 3H2+N2→2NH3 x 0.653 now, you have to use the coefficients to form a ratio between the 2 substances, since they're not in a one to one relationship. aA + bB -> cC moles of C/c = moles of A/a

see i dont understand that
aaronq
  • aaronq
all you have to do is normalize each one by diving the amount of moles by it's respective coefficient \[\frac{ moles of H _{2} }{ 3 }=\frac{ moles of NH _{3} }{ 2 }\]

then solve for whatever you're looking for
