Compute the mass of the solution naoh

Reference no: EM13206224

When 2.5000g of NaOH were dissolved in 49.0g water in a calorimeter at 24.0C, the temperature of the solution went up to 37.1C.

a) is this dissolving process exothermic?

b)Calculate qH2O using q= (sp x m x deltaT) .......... 2685.7096 J (2.68x10^3)

c) Calculate the mass of the solution (NaOH + H2O).......... 51.5g

d) find qrxn for the entire reaction (water and NaOH) as it occured in the calorimeter. use q rxn = q soultion = delta H reaction........ -2822.73 J or -2.82x10^3

e) find qrxn (using part d) for the dissolving of 1.00g NaOH in water.

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