Molarity of the solution measures number of moles of a solute per litre of solution.
Molarity = volume of solution in litres/number of moles of solute dissolved in solution
Volume of solution in litres = 0.86 L
Also, 1.34 mole sample of LiCl dissolves in water
Molarity of the Solution =
In order to solve this problem we need to keep in mind the formula for the <em>boiling point elevation</em>:
Input the data and <u>calculate </u><em><u>m</u></em>:
We now can <u>calculate the number of moles of the substance</u>, using the <em>definition of molarity</em>:
In this case kg of solvent = 90.0 g / 1000 = 0.090 kg
Finally we <u>calculate the molar mass</u>, using the <em>number of moles and the mass</em>:
We are given that
Thickness of membrane,
We have to find the flow rate of sodium ions.
Using the formula
