5.00 g of octane are burned in a bomb calorimeter containing 2.00 * 10^2 g of water. how many Calories of energy are released if the water temperature increases 6.00 degrees C?

  • College chemistry -

    q = mass x specific heat x delta T.

  • College chemistry -

    That's mass H2O x sp.h.H2O x delta T water.

  • College chemistry -

    do i use the 5.00 g or the 2.00 * 10^2 g?

  • College chemistry -

    ok so it'd be
    (2.00*10^2)(6.00 degree C) and then what would be the specific heat?

  • College chemistry -

    specific heat of h2o is 4.184

  • College chemistry -

    i got 5020.8

  • College chemistry -

    you have to convert it from joules to calories and idk that off hand but other then that it looks good so far

  • College chemistry -

    ok, we didn't do joules in class, so hopefully that's what my teacher wants. thank you!
