1- Why is the preferred standard state for the solvent in an ideal dilute solution the Roualt's law standard state set? (1 point) 2- Explain why chemists doing quantitative work using liquid solutions prefer to express concentration in terms of molality rather than molarity. (1 point) becarse molality doegn't depend an the conditions (indepandent) 3- State the source of none ideality in 40%(m/m)CH3CH2OH/H2Osolution (1 point)
