What is the molarity of a 2.50 x 102 cm3 solution containing 560.0 g of C6H12O6?

What's the density of the solution?

mols C6H12O6 = grams/molar mass = ?
volume solution = mass/density
Then M = mols/L solution.

Or did you mean molality =m
If so then
m = mols solute/kg solution = mols from above/0.560 = ?
