#"360 grams"#

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

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

#"n = 2 moles"#

∴ We need 2 moles of glucose to prepare 1 litre of 2M solution.

Molar mass of glucose is #"180 g/mol"#

So, mass of 2 moles of glucose is

#2 cancel"mole" × "180 g"/cancel"mole" = "360 g"#
