WebThe reason HF isn't a strong acid while HCl is a strong acid has to do with charge density of the conjugate base. Charge density controls the reactivity of the conjugate base; charge is what governs chemistry and physics. You'll find that the $\ce{F^-}$ anion is fairly reactive relative to $\ce{Cl^-}$, which, in water, is essentially inert.

Molality is a measure of the number of moles of solute in a solution corresponding to 1 kg or 1000 g of solvent. This contrasts with the definition of molarity which is based on a specified volume of solution. A commonly used unit for molality in chemistry is mol/kg. A solution of concentration 1 mol/kg is also sometimes denoted as 1 molal. The unit mol/kg requires that molar mass be expressed in … Web30 de ene. de 2024 · Molality = Number of moles of solute/Mass of solvent in kg. Molality = 0.1852 mol /0.1 kg = 1.852 mol kg-1.
