When 2.5000g of NaOH were dissolved in 49.0g water in a calorimeter at 24.0 degrees C, the temperature of the solution went up to 37.1 degree C. eq.1. (q=(specific heat)x(mass in g)x(temperature change) q=(shxmx delta t) where delta t= (t final-t initial). the heat is measured in either joules or calories. (1 calorie=4.184 J).

a) calculate the mass of the solution (NaOH+H2O)

b) calculate q solution for the entire reaction (NaOH+H2O) as it occurred in the calorimeter using Eq.1. show calculations and watch sig figs.

c) calculate q reaction for the entire reaction (NaOH+H2O) as it occurred in the calorimeter using Eq.1. show calculation and watch sig figs.

d) Find q reaction (using part c) for the dissolving of 1.00g NaOH in water. (eq 4.(q reaction=-q aqueous solution= delta H reaction))

e) find delta H reaction (using part d) for the dissolving of 1.00 mole NaOH in water.
