17. A coffee cup calorimeter was used to measure the heat evolved when 0.0300molofNaOH(s) was added to 1000mL of 0.0300MHNO3 initially at 23.000C. The temperature of the water the final solution is 4.18J/gC; the density of HNO3 is 1.00g/mL; and the addition of solid does not appreciably affect the volume of the solution.
