Calculate the following quantities, and record them in the table:
the number of moles of citric acid used (Use 192.13 grams/mole as the molar mass of citric acid.)
the heat absorbed by the water, in joules (Use Q = mCΔT, where 15.0 milliliters of water has a mass of 15.0 grams. Use 4.186 joules/gram degree Celsius as water’s specific heat capacity.)
the change in internal energy of the mixture of citric acid and sodium bicarbonate. (Assume that energy absorbed by the mixture of citric acid and sodium bicarbonate is released by the water.)
the reaction enthalpy, in joules/mole
Answer these
Moles of citric acid:
Heat absorbed by water (J):
Change in internal energy (J):
Reaction enthalpy (J/mol):
