please help me. Thanks.Colligative Properties. 1. Draw hand on the grid on your graph what the freezing point bel a cool curve plot for the following data. Indicate is. Label the axes, and show scales on the axes. 0.5 1.0 1.5 10 2.0 2,5 3.0 3.5 4.0 4.5 5.0 5.5 6.0 7.0 8.0 2. Assuming the data above describes a solution of Naci in water, what are: a) the freezing point depression for the solution? b) the molality of the Naci solution? [Ke for water 1.86 ochm (Hint: don't forget that the Naci dissociates to give two particles.)

Explanation / Answer

froom the plot freezing poinnt is -1 deg.c

delT= (0-(-1)} =1 deg.c

delT= kf*m kf= 1.86 deg.c/m

m= molality gnoles/kg of solvent

1= 1.86*m

m= 1/1.86=0.5376 moles of NaCl/kg of solvent
