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
moles NaCl = grams/molar mass = ?
Solve for moles.
molality = mols/kg solvent
Solve for molality
delta T = i*kf*m
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.
