1-Calcular el descenso crioscópico de una solución de ClNa 0,5 molal sabiendo que Kc: 1,87ºC/1- 2-Calcular el punto de congelación de una sc 2 m de glucosa en agua. TºCagua= 0ºC, Kc= 1,86º/m.

3-Calcular el punto de congelación de una sc compuesta por 86g de glucosa (C6H12O6) y 500 gs de agua. Kc=1,86ºC/m.

4-Calcular el descenso crioscopico de una sc de anticongelante 10%m/msv disuelto en agua (C2H4(OH)2).

•what conclusions can you make about the relationship between the volume of a gas and its temperature? • what conclusions can you make about the relationship between the volume of a gas and its pressure? • what possible variables have you not accounted for? as you did the procedures, is it possible that the atmospheric pressure may have changed? if it did change over the course of your experiment, then how would your results have been affected?
