Grade 11 Stoichiometry question

  1. Oct 16, 2011 #1
    1. The problem statement, all variables and given/known data
    What volume of CO2 at 333 K and 90 kPa is produced when 0.4 L of 0.6 M solution of H3PO4 reacts with 36 g of Na2CO3?


    2. Relevant equations



    3. The attempt at a solution
    I calculated the moles for Na2CO3 and H3PO4 but Im lost

    Start with the reaction equation.

    Write the equations, see how many moles of CO2 will be produced, use some gas equation(maybe the perfect gas equation) to calculate how much volume that occupies at this pressure.

    For the record - in English it is called the ideal gas equation.

    Haha, true that. Translating things literally is bound to fail.
    I also saw there's a difference in english, with perfect gases being these that do not change their cp and cv with temp/pressure.
