A concentrated antifreeze solution contains 580. g ethylene glycol mixed with 540. g of water. The weight percent of water in this solution is

Question

Quizplus · Accepted Answer

To find the weight percent of water in the solution, we need to determine the total weight of the solution first:

Total weight of solution = weight of ethylene glycol + weight of water
Total weight of solution = 580. g + 540. g
Total weight of solution = 1120. g

The weight percent of water can now be calculated:

Weight percent of water = (weight of water ÷ total weight of solution) x 100%
Weight percent of water = (540. g ÷ 1120. g) x 100%
Weight percent of water ≈ 48.2%

Therefore, the answer is B.
