## nyland1 Group Title How many grams of H2 are needed produced in 11.13 grams of of NH3 one year ago one year ago

1. aaronq Group Title

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

2. nyland1 Group Title

3H2+N2$3H _{2}+N _{2}\rightarrow2NH _{3}$

3. nyland1 Group Title

ignore the first part

4. aaronq Group Title

okay good stuff, now covert the grams of NH3 to moles

5. nyland1 Group Title

ok so find the molar mass?

6. aaronq Group Title

well yeah, then find the moles moles=mass/molar mass

7. nyland1 Group Title

17.034

8. nyland1 Group Title

.653

9. aaronq Group Title

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

10. nyland1 Group Title

see i dont understand that

11. aaronq Group Title

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
