The yield will be 2 mol of H_2O.

Explanation:

First we need to write a balanced chemical equation:

2H_2+O_2=2H_2O

In this case, the O_2 will be the limiting reagent: we need 2 mol of H_2 for each mole of O_2, but we have 4. There will be some H_2 left over unreacted.

We know from the balanced equation that 1 mol of O_2 will yield 2 mol of H_2O, and since we have 1 mol of O_2 the yield will be 2 mol of H_2O.
