mol of glucose =180

$10\mathrm{\%}\mathrm{ }\left(\frac{\mathrm{W}}{\mathrm{W}}\right)$solution of glucose means$100\mathrm{ }\mathrm{g}$solution contains$10\mathrm{ }\mathrm{g}$glucose.

$\mathrm{Molarity}=\frac{\mathrm{moles} \mathrm{of} \mathrm{solute}}{\mathrm{volume} \mathrm{of} \mathrm{solution}\left(\mathrm{mL}\right)}\times 1000=\frac{{\displaystyle \frac{10}{180}}}{{\displaystyle \frac{100}{1.2}}}\times 1000 \mathrm{M}$
$=\frac{10\times 1.2\times 1000}{180\times 100}=0.67 \mathrm{M}$
