Question

What mass of carbon constitutes a `16.5*g` mass of glucose?

Answer 1

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`
