Question

A container was found in the home of the victim that contained 124 g of ethylene glycol in 420 g of liquid. What was the percentage of ethylene glycol?

Answer 1

29.5%

Step-by-step explanation:

Step 1: Given data

• Mass of ethylene glycol (solute): 124 g

• Mass of liquid (solution): 420 g

Step 2: Calculate the mass percentage of ethylene glycol in the liquid

We will use the following expression.

%m/m = mass of ethylene glycol/ mass of solution × 100%

%m/m = 124 g/420 g × 100% = 29.5%

The mass percentage of ethylene glycol in the liquid is 29.5%.
