    Answer is: the molarity of this glucose solution is 0.278 M.

    m (C₆H₁₂O₆) = 5.10 g.

    n (C₆H₁₂O₆) = m (C₆H₁₂O₆) : M (C₆H₁₂O₆).

    n (C₆H₁₂O₆) = 5.10 g : 180.156 g/mol.

    n (C₆H₁₂O₆) = 0.028 mol.

    V (solution) = 100.5 mL : 1000 mL/L.

    V (solution) = 0.1005 L.

    c (C₆H₁₂O₆) = n (C₆H₁₂O₆) : V (solution).

    c (C₆H₁₂O₆) = 0.028 mol : 0.1005 L.

    c (C₆H₁₂O₆) = 0.278 mol/L.
