1.761 moles NO will be made from 30g of NH3.
Finding the moles of a Substance using Stoichiometry
The balanced reaction is:
4 NH₃(g) + 5 O₂(g) → 4 NO (g) + 6 H₂O
By stoichiometry of the reaction, we have
- 4 moles of NH₃
- 5 moles of O₂
- 4 moles of NO
- 6 moles H₂O
Recall that
Number of moles = Mass/ Molar Mass
We first Find the number of moles in 30g of NH3 ,
Number of moles=30/17.031 g/mol=1.761moles
Now we can say if by stoichiometry
IF 4 moles of NH3 produces 4 moles of NO,
then 1.761 moles of aNH3 will produce = ( 1.761 moles NH3 x 4 moles of NO)/ 4 moles of NH3
= 1.761 moles NO
Therefore, 1.761 moles NO will be made from 30g of NH3.
