Nuclear fusion is the source of energy for stars. besides hydrogen, which other element is most likely also common in stars?

If 34.2 grams of lithium react with excess water, how many liters of hydrogen gas can be produced at 299 kelvin and 1.21 atmospheres? 2 li (s) + 2 h2o (l) yields 2 lioh (aq) + h2 (g)
