Stoichiometry Help??? iwant 2 Know if im doing this right???

Question

this is mole to moles
equation balanced
N2+3H2-->2NH3
if 4.0 mole of H2 rect how many moles of NH3 will be produced??
i got about 2.6mole of NH3
did i do it right please helpppp

Answer 1

Yes! exactly 8/3

You simply take your balanced equation and multiply everything by 4/3 to get the coefficients that you need.

Answer 2

The stoichiometric ratio must remain constant.

1:3:2
a:4:x

4/3 = x/2

x = 8/3 or 2.666 moles

You're absolutely right.
