#0.02M#

Explanation:

We need to know the moles of solute we have in the solution before finding molarity. First we need to convert the 20g of glucose to moles.

#20"g" * "1mol"/"180g"# = 0.1mol

Molarity is represented as moles of solute per unit liter of solution
Thus, it is 0.1mol/5L.

#"0.1mol"/"5L" = 0.02M#
