Calculate the change in boiling or freezing temperature using one the following formulas: ΔTf = Kf * m or ΔTb = Kb* m. Add the value obtained for ΔTb to the standard boiling point of the solvent (ex. 100 C for water) or subtract the value obtained for ΔTf from the standard fre...
Calculate the pH of an alkaline (or basic) buffer solution. You can rewrite the Henderson-Hasselbalch equation for bases: pOH = pKb + log ([B+]/[BOH]), where "pKb" is the base's dissociation constant, "[B+]" stands for the concentration of a base's conjugate acid and "[BOH]" i...
Also, note that the equations above don’t take into account the cost associated with retaining a customer. To get a net value for your CLV, you will also need to calculate this. And if you want to be accurate, you may also want to consider interaction and transactional information for ...

Step 1: Calculate the molality of the NaCl molality (m) of NaCl = moles of NaCl/kg water From theperiodic table, find the atomic masses of the elements: atomic massNa = 22.99 atomic mass Cl = 35.45 moles of NaCl = 31.65 g x 1 mol/(22.99 + 35.45) ...
If we calculate the right-hand side of the accounting equation (equity + liabilities), we arrive at ($50 billion + $120 billion) = $170 billion, which matches the value of the assets reported by the company. What Is the Purpose of the Double-Entry System?
Finite difference method: This model is used to solve differential equations by approximating them with difference equations that finite differences approximate. For options prices, the finite difference method is used to solve partial differential equations typically derived from options pricing formulas, ...

Chemicals can be loosely divided into two extremes: acids and bases. The pH scale measures exactly where a chemical falls between one of those two extremes. The scale measures 0 to 14; the lower the number, the more acidic a substance is. Water, for exam
Example: Calculate the pH of a 0.100 M solution of HCl. Since HCl is a strong acid, it completely ionizes, and the pH of HCl in solution can be found from the concentration (molarity) of the H+ ions, by definition equal to 0.100 M. (The conjugate base of the acid, which is the...
