A 900ml sample of 100m naoh is mixed with 450ml of 100m, Ask an Expert

Academics

A 90.0mL sample of 1.00M NaOH is mixed with 45.0mL of 1.00M H2SO4 in a large Styrofoam coffee cup; the cup is fitted with a lib through which passes a calibrated thermometer. The temperature of each solution before mixing in 22.1 degrees Celcius. After adding the NaOH solution to the coffee cup and stirring the mixed solutions with the thermometer, the maximum temperature measured is 30.3 degrees Celcius. Assume that the density of the mixed solutions is 1.00g/mL, that the specific heat of the mixed solution if 4.18J/(g x degrees celcius), and that no heat is lost to the surroundings.

Calculate the enthalpy change per mole of H2SO4 in the reaction.
