Hey can someone walk me through these stochiometry problems step-by step? Parts of the concept is confusing me and I needed some examples to go by. Thanks in advance.

In the following sythesis reaction how many liters of ammonia at STP, are needed to fully react with 30.mL of 2.1M H2SO4 according to the equation:

2H3+H2SO4=(NH4)2SO4

Typo

The equation should look like this

2NH

_{3}_{(g)} + H

_{2}SO

_{4}_{(aq)} -> (NH

_{4})

_{2}SO

_{4}_{(aq)}Firstly calculate n(H

_{2}SO

_{4}) = 0.03 * 2.1 = 0.063mol

From the equation, the reaction is a 2:1 reaction, hence

n(NH

_{3}) = 0.064 * 2 = 0.126

From there on you can choose to either use PV=nRT or Molar Gas Volume. Personally would choose Molar Gas Volume. Therefore

v(NH

_{3}) = 22.4 * 0.126 = 2.8 L

I want scooby snak!
