What is q (heat) for 1.95 g of NaOH(s) dissolving in 99.5 g of water in a calorimeter with a heat capacity of 30.0 J/K. The temperature change is +5.9 °C and the heat capacity of the solution is 4.07 J/K/g. o -2613 J -2436 J c -224 J O +2613 J o +2436 J C -123592 J O-2566 J When 2.05 g of sodium hydroxide (molar mass = 40.0 g/mol) is dissolved in water in an open calorimeter the measured heat (q) is -2102 J. What is the molar enthalpy change for NaOH dissolving in water? O O O O O O O -1.0 kJ/mol kJ/mol -0.1 -410.1 kJ/mol -41.0 kJ/mol -36.9 kJ/mol O +41.0 kJ/mol
