$% composition = \frac{quantity of stuff}{quantity of stuff + quantity of solvent} \times 100 %$ $"% composition"="quantity of stuff"/"quantity of stuff + quantity of solvent"xx100%$

Explanation:

Most of the time we quote a percentage by mass....which is defined by the given quotient....i.e. $\frac{weight}{weight} \times 100 %$ $"weight"/"weight"xx100%$ . The term $part per million$ $"part per million"$ is for trace quantities in aqueous solution...and refers to the quotient... $\frac{milligrams of solute}{litres of solution}$ $"milligrams of solute"/"litres of solution"$ ...where $1 \cdot L$ $1*L$ $=$ $=$ $1000 \times 1000 \cdot m g = 10^{6} \cdot m g$ $1000xx1000*mg=10^6*mg$ , i.e. one million milligrams....
