Give the meaning of $10\%$ glucose by weight.

(N/A) The expression $10\%$ glucose by weight means that $10 \ g$ of glucose is dissolved in $90 \ g$ of water,resulting in a total mass of $100 \ g$ of the solution.
Mathematically,it is defined as:
$\text{Mass percentage} = \frac{\text{Mass of solute}}{\text{Mass of solution}} \times 100$
$\frac{10 \ g \text{ glucose}}{100 \ g \text{ solution}} \times 100 = 10\%$.
