it is pretty dilute, if you assume the density of the solution is close to 1.00, then the amount of solvent added was 250 grams. Without other information, you have to assume that.
molarity=molessolute/.250kg
molarity=molessolute/.250kg

mols glucose = grams/molar mass = ?
M = mols/0.250 L = ?
I get an answer of 0.16 = M
M = mols/0.250 L = ?
I get an answer of 0.16 = M
