WebMolar and Molal Concentrations: Molarity (M) of a solution is defined as the number of moles of the solute present in one liter of the solution. Molality (m) of a solution is defined as the number of moles of the solute present in one kilogram of the solvent. Molarity is temperature dependent while molality is independent of the temperature. WebMost people probably grew up being told a body’s normal temperature was 98.6 degrees Fahrenheit (or 37 degrees Celsius). That widely accepted number originated from a …
