Use a table to look up the freezing point depression (Kf) or boiling point elevation (Kb) constant for your solvent (See Resources). Every substance has a unique constant that determines how much one mole of solute will decrease the freezing point or increase the boiling point. Calculate the...
Calculating the initial concentration of a solution – otherwise known as molarity – is an important process commonly found in the chemical and biochemical world. Molarity is the number of moles of solute per liter of solution. Therefore, you need to determine how many moles of a solute are i...
How to Calculate Particle Concentration. The particle concentration within a solution describes the number of particles dissolved in the solvent. A solution may contain billions upon billions of particles, so chemists, for convenience, specify the amount
The equation: Posm =2 [Na(+)]+glucose (mg/dL)/18+BUN (mg/dL)//2.8 is also the simplest and best formula to calculate plasma osmolality. The concentration of
You can perform a PPM conversion easily provided you have two quantities in the same unit (or that you can convert into the same unit) or a percentage value. PPM means "parts per million," so to calculate it you divide the amount of the solute by the tot
What are you actually trying to calculate? You say you want to calculate a concentration (of what in what?), but it looks like you're trying to calculate the amount (in g) of analyte in the original sample. If you're not clear what you want to do, you've not much hope of doing...
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. ...
According to the law of dilution, the mathematical product of the initial concentration and the initial volume of a solution is equal to the mathematical product of the final concentration and the final volume of the solution. This law is valid only when the amoun...
This relates the amount of solute in moles with the total volume of the solution expressed in liters. Answer and Explanation: 1 First, you can solve for the number of moles of sucrose contained in the solution by multiplying the molarity wit...
How to Calculate Mole Fractions Using Mass Percent If you know the percent by weight of a solution, you can find the weight of solute. Divide this by its molecular weight to find the number of moles and divide by the volume of solution to find the molarity....
