50 g of NaCL is dissolved into 800 ml H2O.
i need to know if is molarity, g/equivalent, freezing point depression, boiling point elevation or osmolarity. nad how to resolve please give me a hand

  • chemistry -

    moles NaCl = grams/molar mass = ?
    Solve for moles.
    molality = mols/kg solvent
    Solve for molality
    freezing point:
    delta T = i*kf*m
    boiling point:
    delta T = i*Kb*m
    i = 2 in both cases.

    Technically we can't calculate molarity since no density is listed. 800 mL solvent is not the same as 800 mL solution. You need to clarify the g/equivalent for me.
