Answer:
0.0125 moles of NaOH are present
Explanation:
Molarity, M, is an unit of concentration widely used in chemistry. Is defined as the ratio between moles of solute (In this case, NaOH) and liters of solution.
250.0mL are = 0.250L of solution. As the molarity of the solution is 0.05M = 0.05moles / 1L, the moles present are:
0.250L * (0.05moles / 1L) =
0.0125 moles of NaOH are present
