How can you calculate the vapour pressure of water over the solution at 90 degrees Celsius vapour pressure of water at 90 degrees Celsius is 525.8mmHg?
If this solution is a mixture you would use Henry's or Raoult's Law. If this is pure water then the answer is already in the question.
18.6 grams of a solute with molecular mass of 8490 grams are dissolved in enough water to make 1.00 dm3 of solution at 25 Celsius what is the osmotic pressure of the solution?
35.3
An aqueous solution containing a nonvolatile solute will boil above 100 celsius at 1 ATM pressure true or false?
True
A solution is prepared by adding 30 grams of lactose to 110 g water at 55 degrees celsius so what is the partial pressure of water above the solution?
The answer is 116.3 Torr. But I don't know how to solve it. I have the same question.
What is the temperature at which a substance may exist in all three phases?
The triple point of a substance is the temperature and pressure at which all three phases are in equilibrium. The exact temperature and pressure depend upon the identity of the substance.

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 triple point for silver?
The triple point refers the temperature and pressure at which the three phases of silver coexist in the thermodynamic equilibrium. The triple point of silver is 1233.95 degrees Celsius.

True
What is the temperature of ice water in Celsius?
At standard pressure, pure water and ice are in equilibrium at zero Celsius.
What is triple point of water?
The temperature at which all three phases of a substance can exist in equilibrium. This temperature occurs at only one pressure.
Is methane a volatile organic compound?
Volatile means that a substance evaporate easily.Methane is volatile because:- molecules of methane are bonded by dispersion forces- dispersion forces are the weakest form of intermolecular bonding, meaning that there is only a small amount of energy (or heat) required to break the weak dispersion forces between the methane molecules

The osmotic pressure of a 0.010 M MgSO4 solution at 25 degrees Celsius is 0.318 ATM Calculate i the van't Hoff factor for this solution?
osmotic pressure=CRT x i 25 C to Kelvin = 298K 0.318atm= 0.010 M x 0.08206 x 298 K answer= 1.30
What is the methanol boiling point?
Methanol, also known as methyl alcohol CH40, is the simplest alcohol and is light, volatile, colorless, flammable liquid. It has a boiling point of 64.7 C = 148.4 F = 337.8 K, at standard pressure.
How can water be made to boil at 105 degrees Celsius instead of 100 degrees Celsius?
Water could be made to boil at 105 degrees C instead of 100 degrees C by adding a solute to the water. You can also raise the boiling point of water by moving to a higher elevation or putting it under higher pressure.
