[b]1. How many liters of hydrogen gas will be produced at 280 K and 96 kPa if 1.74 of Na reacts with excess water according to the following equation.

2Na + 2H[itex]_{2}[/itex]O [itex]\rightarrow[/itex]2NaOH + H[itex]_{2}[/itex]

Im gussing I am going to have to find the number of moles of H[itex]_{2}[/itex] before I can do anything.

So I am thinking that since there is 1.74 mol of Na that is going to be the number of moles of H[itex]_{2}[/itex]. Is that right?

Use [sub][/sub] and [sup][/sup] tags to format subscripts and superscripts (so H[sub]3[/sub]O[sup]+[/sup] yields H3O+) - don't use inline LaTeX for formatting single characters.

You are wrong, but not far from the correct answer. You forgot to take stoichiometric coefficients into account. Please read about stoichiometric calculations.
