How the Henderson Hasselbalch equation is derived? The following equation, which relates the pH of an aqueous solution of an acid to the acid dissociation constant of the acid, is known as the Henderson-Hasselbach equation. The Henderson-Hasselbach equation is derived from the definition of the acid dissociation constant as follows. How is the formula for […]

How do you find the Y intercept? How Do You Find the X- and Y-Intercepts of a Line in Slope-Intercept Form? To find the x-intercept of a given linear equation, plug in 0 for ‘y’ and solve for ‘x’. To find the y-intercept, plug 0 in for ‘x’ and solve for ‘y’. How do you […]

How do you calculate EVA in Excel? Economic Value Added (EVA)EVA = NOPAT – (WACC * capital invested)WACC = Weighted Average Cost of Capital. Capital invested = Equity + long-term debt at the beginning of the period.Tax charge per income statement – increase (or + if reduction) in deferred tax provision + tax benefit of […]

How do you find the radius of a circle? Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the […]

What is the formula for calculating molecular weight? Sample Molecular Weight Calculation Using the periodic table of the elements to find atomic weights, we find that hydrogen has an atomic weight of 1, and oxygen’s is 16. In order to calculate the molecular weight of one water molecule, we add the contributions from each atom; […]
