Chemistry

Please use sig figs and dimensional analysisand explain process!

1. Dissolve 69.0 g NaNO2 in 1.00 x 102 mLH2O.

(a) If the temperature of the solution is 100°C, what is thevapor pressure above the solution? The density of H2O at100°C is 0.9591 g/mL.

(b) Calculate the change in the boiling point of the solution,and calculate the boiling point of the aqueous solution.

(c) Calculate the freezing point of the solution. The density ofH2O at 0°C is 0.9998 g/mL.

(d) Which change is greater, the boiling point elevation or thefreezing point depression?

(e) Estimate the osmotic pressure at 25 °C for the solution.Assume that dissolved sodium nitrite does not affect the volume ofthe solution.
