    Explanation:u

    Concentration = moles * volume

    The volume = 0.25litres

    Moles=0.75

    Concentration = 0 75*0.25 = 0.1875mol/litres

    The concentration of the KCl solution is 3.0 M

    Explanation:

    Step 1: Data given

    Volume of KCl = 0.25 L

    Number of moles KCl = 0.75 moles

    Molar mass KCl = 74.55 g/mol

    Step 2: Calculate concentration of KCl

    Concentration KCl solution = moles KCl / volume solution

    Concentration KCl solution = 0.75 moles / 0.25 L

    Concentration KCl solution = 3.0 M

    The concentration of the KCl solution is 3.0 M
