How does a solution containing a chemical with a high vapor pressure be low in volatility?
Well vapor pressure also depends on the mole fraction of a substance. Vapor pressure= Mole fraction* Total pressure of the solution. If the Mole fraction of a volatile substance in the solution is decreased its vapor pressure increases. Thus the volatility of the substance barely plays the role. Of course, if the solution has no volatile substance there cannot be any vapor pressure in the container.
What happens to vapor pressure as more solute such as sugar is added to a solution?
The vapor pressure decreases
What are the three properties of a solution?
1. Vapor pressure lowering: the decrease in vapor pressure with increasing the number of solute molecules in solution. 2. Boiling point elevation: the increase in boiling point with increasing number of solute molecules in solution. 3. Freezing point depression: the decrease in freezing point with increasing number of solute molecules in solution. 4. Osmotic pressure
What is the vapor pressure considered a chemical or solution considered an explosive hazard?

How does the addition of solute affect freezing and boiling point and vapor pressure on a solvent?
A non-volatile solute affects increases osmotic pressure. This is a colligative property. There will be a higher osmotic pressure required to prevent the solvent from flowing into the solution because the solvent has a higher chemical potential without solute in it.
How will the vapor pressure of pure water compare to an aqueous solution of sodium chloride?
The solution's vapor pressure will be lower.

A pure solvent has a vapor pressure the vapor pressure of a solution A.EQUALTO B.LOWER THAN C.higher than?
A solution has a higher vapor pressure than a pure solvent. This is why salt water boils faster than pure water.
What happens to vapor pressure if sugar is added to a solution?
When you add a teaspoon of honey to water with vapor pressure, it will reduce the vapor pressure. The sugar in the honey leads to the pressure going down.
Dissolving solutes into a solution will?
lower vapor pressure
What pressure for a chemical or solution is considered an explosive hazard?
when the vapor pressure is greater than 5 mm

What states that the magnitude of vapor pressure reduction is proportional to the solution's concentration?
Raoult's Law
What is the boiling point of an aqueous solution that has a vapor pressure of 18.5 at 25 degrees Celsius?
108.7
What is the vapor pressure on the Material Safety Data Sheet for a chemical or solution that is considered an explosive hazard?
The pressure is greater then 10 mm.
