Answer to Question #106378 in General Chemistry for Mario

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
