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

## Solutions

##### Expert Solution

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
