1) At 24 C the vapor pressure of water is 3 kPa. The vapor pressure of water over a sample is 2 kPa, what is the water activity of the sample? 2) The water activity above a saturated NaCl solution is 0.75. If a sample is enclosed in a jar with the NaCl solution and equilibrium is achieved, what is the water activity of the sample? NaCl and the sample are in separate containers within the jar.
