Question

If the toxic quantity is $1.5g$of ethylene glycol per $1000g$of body mass, what percentage of ethylene glycol is fatal?

Short answer

The percentage of ethylene glycol is fatal is $0.15\%$.

Step-by-step solution

Given Information

We need to find the percentage of ethylene glycol is fatal.

Simplify

Consider that the toxic quantity is $1.5g$of ethylene glycol per $1000g$of body mass, and determine what percentage of ethylene glycol is fatal.

To determine a percentage, divide into the parts by the total and multiply by $100\%$.

$$\begin{gathered} \text{P}=\frac{Part}{Whole}\times 100 \\ =\frac{1.5}{1000}\times 100 \\ =1.5\times {10}^{-3}\times 100 \\ \approx 0.15\text{\%} \end{gathered}$$

So, approximately $0.15\%$ethylene glycol is fatal.
