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$_{2}$O $\rightarrow$2NaOH + H$_{2}$

Im gussing I am going to have to find the number of moles of H$_{2}$ 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$_{2}$. Is that right?

Use [noparse] and [/noparse] tags to format subscripts and superscripts (so [noparse]H3O+[/noparse] 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.
