What is the concentration of LiCl (lithium chloride) when 2.5g of LiCl are dissolved in water and the volume of the final solution is 45.0mL? The formula for %(m/v) is shown below.
Answer:
Given,
To determine the concentration of Licl
weight of the lithium chloride = 2.5g
Molar mass of the lithium chloride = 42.394g/mol
Now,
Mole of the Lithium chloride = mass/volume
Moles of Licl = 2.5/42.394= 0.058971
Now consider,
Concentration = mole/volume in litre
Concentration = 0.058971/(45*10^-3)
Licl concentration= 1.3105mol/litre

1. If the concentration of AgNO3 is 0.00503 M and the concentration of the LiCl solution is 0.00387 M, use the stoichiometry of your equation to predict the volume of lithium chloride needed to react with 9.98 mL of the silver nitrate solution. Set up this calculation in Excel using good labels and equations so you can change the numbers accordingly in lab. (Paste screen capture of the excel sheet showing formulas in the designated space.) Failure to do this...
