Question

What volume at STP would be required to react with 0.100 mol of hydrogen to produce ammonia?

Answer 1

The balanced reaction equation is : N₂(g) + 3 H₂(g) 2 NH₃(g)

Given : moles H₂ = 0.100 mol

moles N₂ required = (moles H₂) * (molar ratio of N₂ to H₂)

moles N₂ required = (moles H₂) * (1 mole N₂ / 3 moles H₂)

moles N₂ required = (0.100 mol) * (1/3)

moles N₂ required = (0.100 mol) * (0.333)

moles N₂ required = 0.0333 mol

volume N₂ required = (moles N₂ required) * (molar volume of ideal gas at STP)

volume N₂ required = (0.0333 mol) * (22.4 L/mol)

volume N₂ required = 0.767 L

volume N₂ required = 767 mL
