Question

A container was found in the home of the victim that contained 131 g of Ethylene glycol in 440 g of liquid. What was the percentage of ethylene glycol?

(a) 10%
(b) 20%
(c) 30%
(d) 40%

Answer 1

The percentage of ethylene glycol in the solution is calculated by dividing the mass of ethylene glycol by the total mass of the liquid and multiplying by 100, resulting in approximately 30%.

Step-by-step explanation:

To calculate the percentage of ethylene glycol in the solution, you need to divide the mass of ethylene glycol by the total mass of the solution and then multiply by 100 to get the percentage.

The formula to calculate the percentage is:

Percentage of ethylene glycol = (mass of ethylene glycol / total mass of the solution) × 100

Using the given values:

Percentage of ethylene glycol = (131 g / 440 g) × 100 = 29.77%

Therefore, the closest answer to the exact percentage is 30% (c).
