Q. 1.29 - An Introduction to General, Organic, and Biological Chemistry

Question

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

Step-by-Step Solution

Answer

The  ethylene glycol percentage is $27\%$.

Step 1: Given Information

We need to find  the percentage of ethylene glycol.

Step 2: Simplify

A container was found in the home of the victim that contained  $120 g$ 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 $450 g$ of liquid.
