If you don't know the concentrations of your initial solutions, calculate molarity by dividing the number of moles in a solute by the volume of the solution in liters. For example, the molarity of a 0.6 moles of NaCl dissolved in 0.45 liters is 1.33 M (0.6 mol ÷ 0.45 L). Do this...
Molarityis one of the most common units of concentration. It is used when the temperature of an experiment won't change. It's one of the easiest units to calculate. You get the mass of solute for the solution, mix the solute with a known volume of solvent, and divide mass by volume ...
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...
Use this formula to calculate ionic strength: I= 1/2 n∑i (CiZi )squared, where "I" represents ionic strength, "n" represents the number of ions in solution, "i" represents the specific ion in solution, "Ci" represents the concentration to the /th species, such as moles per liter, ...

To calculate the pH of a buffer solution, the Henderson-Hasselbalch equation is used, pH = pka + log(acid/base). If working with a weak acid and conjugate base, the pka is found and plugged into the concentrations for each added to the solution.What...
A lot of the wastewater and air quality samples have concentrations that are below the analytical reporting limit of the laboratory. These are called "non-detects" and make it impossible to compute the sample mean concentration. When zero is substituted for each non-detect, the standard may not...
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. ...
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
Calculate and list the steps on how a 5M Tris solution will be used to prepare 200 mL of the following solutions: 1 M, 100 mM, 10 mM, 1 mM and 0.1 mM. How to prepare 1 ml of GTE buffer (50mM glucose,25mM Tris Hcl PH 8.0,...
