If you burn 0.200 g of C(graphite) in an excess of O2 to give CO2, the temperature of the calorimeter, which contains 775 g water, increases from 25.00 degrees C to 27.38 degrees C. The heat capacity of the bomb is 893 J/K. What quantity of heat is evolved per mole of C?
C (graphite) + O2 yields CO2
q = (massH2O x specific heat H2O x delta T) + (893*delta T) = ?
Then ?/0.200 = heat/gram
and (heat/gram) x 12 = heat/mol
