Question

A container was found in the home of the victim that contained $120g$of ethylene glycol in $450g$of liquid. What was the percentage of ethylene glycol? Express your answer to the ones place.

Short answer

The ethylene glycol percentage is$27\%$.

Step-by-step solution

Given Information

We need to find the percentage of ethylene glycol.

Simplify 

A container was found in the home of the victim that contained $120g$of ethylene glycol in $450g$of liquid. Determine what was the percentage of ethylene glycol.

To determine a percentage, divide into the parts by the total and multiply by $100\%$.
$$\begin{gathered} \text{P}=\frac{Part}{Whole}\times 100 \\ =\frac{120}{450}\times 100 \\ =0.2667\times 100 \\ =26.67\text{\%}\approx 27\text{\%} \end{gathered}$$

So, approximately $27\%$ethylene glycol was in the $450g$of liquid.
