Question

If 14.5 grams of sodium nitrate dissolves in 100 cubic centimeters of water and the temperature goes from 26 degrees Celsius to 23 degrees Celsius, calculate : a) the change in temperature (Make sure to write the units just like seen in the problem) *

Answer 1

Solubility=14.5g/100cc

change in temperature, $dT= Tf-Ti$

Tf=23⁰C

Ti=26⁰C

dT=23-26 =-3⁰C
