The average lithium ion concentration in seawater is 0.18 ppm. What is the molality of Li+ in seawater?

Interpretation Introduction

Interpretation: The molality of Li+ in sea water to be identified.

Concept introduction:

Molality: The amount of solute (mol) per kilogram of solvent.

Concentration (C, mol/kg) =  molality of solute = Amount of solute (mol)Mass of solvent (Kg)

Explanation

Given data:

1ppm=1mg/kg,0.18 ppm = 0.18 mg/kg = 0.18 ×10-3g/kg= 0.18 ×10-3g/L(massoflithiumionsin1Lofwater).

The molality:

Molality of a solute is defined as the amount of solute dissolves in kilogram of solvent.

Molality=molesofsoluteMassofsolventinkg
