# How many grams of hydrogen are in 22.60 g of C_6H_12O_6?

Sep 28, 2016

Approx. $1.5 \cdot g$.

#### Explanation:

We work out (i) the amount of moles of sugar:

$\frac{22.60 \cdot g}{180.16 \cdot g \cdot m o {l}^{-} 1}$ $=$ $0.1254 \cdot m o l$

and (ii), the equivalent mass of hydrogen in this molar quantity:

$0.1254 \cdot m o l \times 12 \times 1.00794 \cdot g \cdot m o {l}^{-} 1$ $=$ ??g.

Why did I multiply the molar quantity of sugar by $12$?
