1.How much water would be needed to completely dissolve 1.79 Lof the gas at a pressure of 720 torrand a temperature of 21 âˆ˜C? Agas has a Henry's law constant of 0.183 M/atm .
2.To what volume should you dilute 40.0 mL of a 4.45 M KIsolution so that 23.5 mL of the diluted solution contains 3.15 g ofKI?
3. The solvent for an organic reaction is prepared by mixing70.0 mL of acetone (C3H6O) with 49.0 mLof ethyl acetate (C4H8O2).This mixture is stored at 25.0 âˆ˜C. The vapor pressure and thedensities for the two pure components at 25.0 âˆ˜C are given in thefollowing table. What is the vapor pressure of the storedmixture?
Compound Vapor pressure
(mmHg) Density
(g/mL)
acetone 230.0 0.791
ethyl acetate 95.38 0.900
