Approx. $6.6*g$

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.......

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

What mass of carbon constitutes a 16.5*g16.5*g mass of glucose?
