#"85.5 g"#

Explanation:

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

#"0.25 M" = "n"/"1 L"#

#"n = 0.25 mol"#

So, we need #"0.25 mol"# of sucrose to make #"0.25 M"# solution.

# #

Molar mass of sucrose #("C"_12"H"_22"O"_11) = "342 g/mol"#

Mass of #"0.25 mol"# sucrose is

#0.25 cancel"mol" × 342 "g"/cancel"mol" = "85.5 g"#
