An experiment is carried out where 13.9 g of solid NaOH is dissolved in 250.0 g of water in a coffee-cup calorimeter. Dissolutio

n is not a chemical reaction, but is a chemical process: NaOH(s) → Na+(aq) + OH-(aq) The mixture can be assumed to have the same specific heat capacity as liquid water (4.18 J g-1 ºC-1). What is the mass of the surroundings where the temperature is being measured in the experiment?

Answer:

263.9g

Explanation

Total mass of solution= mass of solute + mass of solvent = 13.9+250g =263.9g

Mass of surrounding= mass of calorimeter= 263.9g
