What volume (mL) of sulfur dioxide can be produced by the complete reaction of 3.82 g of calcium sulfite with excess HCl, when the final SO2 pressure is 827 torr at 44 degrees celsius?

  • chemistry - ,

    1. Write the balanced equation.
    2. Convert 3.82 g CaSO3 to moles. #moles = grams/molar mass.
    3. Using the coefficients in the balanced equation, convert moles CaSO3 to moles SO2.
    4. Use PV = nRT to convert moles SO2 to volume (in liters) then convert L to mL. Don't forget T is in Kelvin.
    Post your work if you get stuck.
