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 example, water has a freezing point of 0 degrees Celsius. Step 2 Calculate th...
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...
Chemistry problems often require more than one equation. For instance, you may need to calculate molality before you can put it into the freezing point depression equation. Molality is equal to amount of the solute in moles over the mass of the solvent in kilograms. References Georgia State Uni...
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...

If you blow out your lines properly, you shouldn’t have to worry about them freezing. But it can sometimes be challenging to get every drop of water out of the lines. Or maybe you’d rather take a quicker route. Either way, you can use antifreeze. ...
BASF, a leading chemical company, offers product carbon footprints (PCFs) for its pharma product portfolio upon customer request. The methodology used to calculate these PCFs is certified according to international standards. Moreover, BASF can support customers by ...
As the battery discharges the voltage will sag down to 10 volts or lower. Q: Can a car battery freeze when it gets too cold?A: When a lead acid battery is fully charged the electrolyte is sulfuric acid with a freezing point of below -40°C. When the battery is fully discharged all...
In a chemical reaction, reactants that are not used up when the reaction is complete are called excess reagents. To calculate the excess reagent, you need to find molecular weight then work out molarity.
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 ...
