First, we need to calculate the amount of solute in moles: moles = Molarity x Volume (in liters) moles = 0.189 mol L^-1/L x 0.500 L moles = 0.0945 mol L^-1 Then, we can use the molar mass of KOH to convert moles to grams: grams = moles x molar mass grams = 0.0945 mol L^-1 x 56.11 g/mol grams = 5.306 g Therefore, the answer is D, 5.30 g.
