How would you prepare:
a.) 250 mL of .1 M KCl
b.) 250 mL of .10 M BaCl2
Molarity is defined as the Number of Moles of Solute divided by the Solution Volume (Liter/s). So to create a molar solution the steps are:
1.Calculate the molar mass of potassium chloride:
Potassium + chloride = ...
Creating molar solutions of KCl and BaCl2.
