Homework Help: Gas Laws

  1. Mar 22, 2012 #1
    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 [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.
