    The number of moles can simply be calculated by the product of Molarity and Volume in L, therefore:

    number of moles = (2.26 moles / L) * 0.0152 L

    number of moles = 0.0344 moles

    The molar mass of KOH is 56.11 g/mol, therefore the mass is:

    mass = 0.0344 moles * 56.11 g/mol

    mass = 1.93 g
