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, ...
When calculating the total number of outcomes, we sometimes need to use a permutation. A permutation is a method to calculate the number of events occurring where order matters. To calculate a permutation, we will need to use the formula nPr = n! Read How to Calculate the Probability of ...
Negatively charged ions are calledanions. What about positively charged ions? They are calledcations. Take a look at this example of how a cation forms: Magnesium is atomic number 12. That means it has 12 electrons and 12 protons. Now, how are the elections configured, and how many electron...

The COUNTIF function counts values that equal a condition, however, it can also count multiple conditions but we must enter this formula as an array formula in order to calculate multiple values in one cell. COUNTIF(D14:D15, B3:B12)>0 returns {0;0;1;1;0;0;1;1;0;0}. This array...
Calculate the molarity of the solution. Molarity is equal to the number of moles of solute divided by the number of liters of solvent, so divide the number of moles by the number of liters of solution to find the molarity. Step 3 Determine whether the solute dissociates as it dissolves....
