calculate the vapor pressure lowering at 40C of a 70-m ammonium sulphate solution. given that the vapor pressure of water is 55.4 torr at 40C.
Added by Mark B.
Step 1
To calculate the mole fraction of ammonium sulphate, we need to know the molar mass of ammonium sulphate (NH4)2SO4, which is 132.14 g/mol. First, calculate the moles of ammonium sulphate in 70g of the solution: 70g / 132.14 g/mol = 0.529 moles of (NH4)2SO4 Next, Show more…

20. A solution of ammonium sulfate in 180 g water has a vapor pressure of 37.5 torr at 25 ℃. What is the mass of the solute in this solution? The vapor pressure of pure water is 50 torr at 25 ℃. 146.7 g What would be the vapor pressure of this solution at 65 ℃? The vapor pressure of pure water is 95 torr at 65 ℃. 71.25 torr 21. A solution is formed by dissolving 125.0 g of NaCl in 1200.0 g of H2O. What is the vapor pressure of the solution at 25 ℃ if the vapor pressure of pure H2O is 38.8 mmHg at 25 ℃? 36.44 mmHg
