Acid-Base Calculations The Ion-Product Constant for Water‚ Kw Water undergoes ionization to a small extent: H20(l) H+(aq) + OH–(aq) The equilibrium constant for the reaction is the ion-product constant for water Kw: (1) This is a key equation in acid-base chemistry. Note that the product of [H+] and [OH–] is a constant at a given temperature (Eq(1) value is for 25oC). Thus as the hydrogen ion concentration of a solution increases‚ the hydroxide ion concentration decreases

Calorie Calculation Exercises 1. A serving of two cookies has 150 kcal and 12 grams of fat. What percentage of total calories is fat? 1) Divide fat calories by the total kilocalories 2) Fat = 9kcal/g 3) 12g x 9kcal/g = 108kcal/g 4) 108kcal / 150kcal = .72 5) .72 x 100 = 72% total calories from fat 2. How many grams of protein are in a 2400kcal diet with 15% of total kcal from protein? 1) Grams / total kcal = total percentage of kcal from protein 2) Protein

How to Calculate Preferred Dividends Preferred stock (or preference shares) is a special class of stock that pays a fixed dividend set at the time of issuance. Also‚ preferred dividends must be paid before common stock dividends. To calculate the dividends for preferred stocks‚ you need to multiply the par value of the shares by the dividend percentage.
