Question

Nitrogen gas reacts with hydrogen gas to produce ammonia (NH₃) gas. How many liters of NH₃ can be produced at 0.93 atm and 24 °C from a 16.0-g sample of nitrogen gas and an excess of hydrogen gas?  N₂(g) + 3H₂(g) à 2NH₃(g)

Answer 1

To provide some context, your final answer will come from the formula PV = nRT

You've been given P (pressure) and T (Temperature, needs to be converted to kelvin). R is a constant

You are ultimately trying to find volume but from the equation above, we are still missing n (number of moles). we can find this from the other information given.

From the balanced equation, 1 mole of nitrogen gas yields 2 moles of ammonia and so, we can get the moles of N₂ by dividing the grams given by its molar mass (don't forget, there are 2 nitrogen atoms) and then apply the mole ratio to get moles of ammonia.

When we get n,we would plug it into the equation above and you should get the answer you're looking for.
