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?

29.5%

Explanation:

Step 1: Given data

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%.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
