Using the formula:

moles (n) = Molarity (M) x Volume (L)

We plug in the values:

n = 6.00 M x 0.250 L = 1.50 moles

To calculate the mass of solute, we use the molar mass of NaOH, which is 40.00 g/mol:

mass = moles x molar mass
mass = 1.50 mol x 40.00 g/mol = 60.0 g

Therefore, the correct answer is B.
