To determine the vapor pressure of a solution, one can use Raoult's Law, which states that the vapor pressure of a solution is directly proportional to the mole fraction of the solvent in the solution. By knowing the mole fraction of the solvent and the vapor pressure of the pure solvent, one can calculate the vapor pressure of the solution.

How can one determine the boiling point from vapor pressure?
To determine the boiling point from vapor pressure, one can use the Clausius-Clapeyron equation, which relates the vapor pressure of a substance to its temperature. By plotting the natural logarithm of the vapor pressure against the reciprocal of the temperature, the boiling point can be determined as the temperature at which the vapor pressure equals the atmospheric pressure.
How can one determine the normal boiling point by using the vapor pressure and temperature?
To determine the normal boiling point using vapor pressure and temperature, one can plot a graph of vapor pressure versus temperature and identify the temperature at which the vapor pressure equals the standard atmospheric pressure of 1 atm. This temperature corresponds to the normal boiling point of the substance.
How can one determine the boiling point from a vapor pressure graph?
To determine the boiling point from a vapor pressure graph, look for the point where the vapor pressure curve intersects the horizontal line representing atmospheric pressure. This intersection point indicates the temperature at which the liquid boils.

How can one determine the osmotic pressure of a solution?
To determine the osmotic pressure of a solution, you can use the formula: iMRT, where is the osmotic pressure, i is the van't Hoff factor, M is the molarity of the solution, R is the ideal gas constant, and T is the temperature in Kelvin. By plugging in the values for these variables, you can calculate the osmotic pressure of the solution.
How can one estimate osmolarity and what methods are used to do so?
One can estimate osmolarity by measuring the concentration of solutes in a solution. This can be done using methods such as osmometry, freezing point depression, and vapor pressure osmometry. These methods help determine the osmolarity of a solution by measuring the effect of solutes on the physical properties of the solution.
Will increasing the P total of a gas mix over the vapor pressure of one the gases vapor pressure force that constituent into the liquid phase if the partial pressure of the gas itself is not exceeded?
No, it will not condense if its partial pressure does not exceed its (maximum) partial pressure of the component's liquid (or solution) at the same(!) temperature.
How can one calculate the vapor pressure deficit (VPD) using temperature and relative humidity?
To calculate the vapor pressure deficit (VPD), subtract the actual vapor pressure (e) from the saturation vapor pressure (es) at a given temperature. The actual vapor pressure can be calculated using the relative humidity (RH) and the saturation vapor pressure can be determined from the temperature. The formula is VPD es - e, where es saturation vapor pressure and e actual vapor pressure.
Which of the following substances is not listed in order of increasing vapor pressure?
The substance that is not listed in order of increasing vapor pressure is the one that does not follow the pattern of lower to higher vapor pressure.
