Look up the freezing point of the liquid (solvent) for which you are calculating the new freezing point. You can find the freezing point of any chemical on the material safety data sheet that accompanies it. For
This example problem demonstrates how to calculate freezing point depression using a solution of salt in water. Key Takeaways: Calculate Freezing Point Depression Freezing point depression is a property of solutions where the solute lowers the normal freezing point of the solvent. Freezing point depres...
Calculate the number of moles of water in 600 grams of water (H2O). Find hydrogen and oxygen on the periodic table. Step 2 Set up the following equation relating grams to moles: x moles H2O = (1 mole H2O/18 grams H2O) x (600 grams H2O) Step 3 Solve the equation in Step 2 to ...
How to calculate enthalpy of vaporization?Heat of Vaporization:The heat of vaporization is the amount of energy associated with the phase change of 1 mol substance from liquid to gas at its boiling point. The unit of heat vaporization is kJmol....

If they know the star's brightness and the distance to the star, they can calculate the star's luminosity: [luminosity = brightness x 12.57 x (distance)2]. Luminosity is also related to a star's size. The larger a star is, the more energy it puts out and the more luminous it is...
Many commercial thermometers contain alcohol because alcohol has a low freezing point. As the temperature of the alcohol increases, it expands and causes the level within the thermometer to rise. The level of the alcohol corresponds to the printed lines/numbers on a thermometer indicating the temper...
test to determine whether fuel is classified as Jet A or Jet A-1. The main difference is freezing point, with Jet A-1 offering a lower maximum freezing point than Jet A. This makes Jet A-1 fuel better suiter to long haul flights that reach high altitudes and travel through polar ...
