#1/12\ "M"#

Explanation:

#"Molarity" = "Moles of solute"/"Volume of solution (in litres)"#

Initial moles of solute is

#"n = 0.251 M × 0.125 L = 0.03125 mol"#

New volume of solution #"= 125 mL + 250 mL = 375 mL = 0.375 L"#

New Molarity is

#"Molarity" = "0.03125 mol"/"0.375 L" = color(Green)(1/12\ "M")#
