Answer:
0.20 Moles
Solution:
Data Given:
Molarity = 2.0 mol.L⁻¹
M.Mass = 74.55 g.mol⁻¹
Volume = 100 mL = 0.1 L
Formula Use:
Molarity = Moles ÷ Volume
Solving for Moles,
Moles = Molarity × Volume
Putting values,
Moles = 2.0 mol.L⁻¹ × 0.1 L
Moles = 0.20 mol
Preparation of 2 M KCl Solution:
Take 0.2 moles of KCl and pour it into a 100 mL empty volumetric flask. After that add distilled water upto the mark of 100 mL. The concentration of resulting solution will be 2.0 M.
