Answer:

Approx. #6.6*g#

Explanation:

We (i) work out the molar quantity of glucose,

i.e. #(16.5*g)/(180.16*g*mol^-1)=0.0916*mol#.

And (ii) since the molecular formula of #C_6H_12O_6#, there are thus #6xx0.0916*mol# of CARBON in the sample, which gives a mass of.......

#6xx0.0916*molxx12.011*g*mol=??*g#
