Explanation
Molecular mass of glucose ($$C_6H_{12}O_6) = (6\times 12) + (12\times 1) + (6\times 16) =180\ g $$
Empirical formula of glucose will be $$CH_2O$$.
So, empirical formula weight of glucose is,
$$ 12 + 2\times 1 + 16 = 30 g $$
$$\therefore$$ Ratio of molecular mass to empirical formula weight is,
$$\dfrac{180 g}{30g}$$ $$= 6$$
Hence, option $$C$$ is correct.
