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!
