The quarts of the antifreeze solution required to achieve 50% content of the antifreeze solution is 1/2.
Data and Calculations:
The capacity of the car radiator = 16-quarts
Antifreeze solution content = 40% or 6.4 quarts (16 x 40%)
Therefore, to fill the radiator with 50% antifreeze solution, 8/16 or 1/2 (16 x 50%) should be the quarts of the antifreeze solution.
Thus, the quarts of the antifreeze solution required to achieve 50% content of the antifreeze solution is 1/2.
