SSSSS [86.1K]

Answer:

m_{NH_3}=21.6gNH_3

Explanation:

Hello there!

In this case, in agreement to the given chemical reaction, it is possible for us to calculate the mass of NH3 required to remove 57.0 g NO via the stoichiometry based off the 4:6 mole ratio between them:

m_{NH_3}=57.0g NO*\frac{1molNO}{30.01gNO}*\frac{4molNH_3}{6molNO}  *\frac{17.03gNH_3}{1molNH_3} \\\\m_{NH_3}=21.6gNH_3

Best regards!
