Solutions — विलयन

Molarity, molality, mole fraction, Henry, Raoult, and colligative (ΔTb, ΔTf, π). Van’t Hoff i for electrolytes. A non-volatile solute lowers vapour pressure. Ideal versus non-ideal is the enthalpy/volume story. Write the formula the question named — molality is not molarity. You are on Solutions (Short answers), page 1 of 1 — 2 questions in this filter. Short answers are two-to-four line NCERT points — definition, reason, or a small numerical. Write in the language your school paper uses (Hindi or English) then match the hidden paragraph.
