Question

Equation to find mass of sodium bicarbonate using normality

Answer 1

concentration measures the amount of a dissolved compound (solute) in a solution. Commonly used molar concentration, or molarity, represents the number of moles of the solute in 1L (liter) of the solution. Normality (denoted as “N”) is similar to molarity, but it refers to the number of chemical equivalents rather than moles. For instance, one molecule of sulfuric acid, H2SO4, produces two hydrogen ions in the solution, and hence can react with two molecules of another compound. As a result, one molar solution of H2SO4 will have the normality of 2. As an example, calculate the mass (in grams) of H2SO4 in 240ml of the 2.5 normal (N) solution
