Answer:
![1.56 \,\,mol/L](https://tex.z-dn.net/?f=1.56%20%5C%2C%5C%2Cmol%2FL)
Explanation:
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
So,
Molarity of the Solution = ![\frac{1.34}{0.86}=1.56 \,\,mol/L](https://tex.z-dn.net/?f=%5Cfrac%7B1.34%7D%7B0.86%7D%3D1.56%20%5C%2C%5C%2Cmol%2FL)

Answer:
Volume of water added = 148.4 mL
Explanation:
Given data:
Initial volume = 424 mL
Initial molarity = 0.189 M
Final molarity = 0.140 M
Volume of water added = ?
Solution:
Formula:
M₁V₁ = M₂V₂
0.189 M×424 mL = 0.140 M×V₂
V₂ = 0.189 M×424 mL /0.140 M
V₂ = 80.136 M.mL / 0.140 M
V₂ = 572.4 mL
Final volume of solution is 572.4 mL.
Volume of water added = Final volume - initial volume
Volume of water added = 572.4 mL - 424 mL
Volume of water added = 148.4 mL
