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

Jun 8, 2017

Approx. $6.6 \cdot g$

#### Explanation:

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

i.e. $\frac{16.5 \cdot g}{180.16 \cdot g \cdot m o {l}^{-} 1} = 0.0916 \cdot m o l$.

And (ii) since the molecular formula of ${C}_{6} {H}_{12} {O}_{6}$, there are thus $6 \times 0.0916 \cdot m o l$ of CARBON in the sample, which gives a mass of.......
