How many quarts of pure antifreeze must be added to 3 quarts of a 10\% antifreeze solution to obtain a 50\% antifreeze solution?

maybe), in order to obtain 50\% concentration, we need to have the as much solute as the solvent. So, adding 1.2 quarts (2.1 – 0.9 = 1.2) of pure antifreeze will do the job.

How many quarts of pure antifreeze must be added to 9 quarts of a 20\% antifreeze solution to obtain a 40\% antifreeze solution hint pure antifreeze is 100\% antifreeze?

The answer is . 9 quarts. Do . 9qts +1.8qts (from the starting mixture) = 2.7.

How much antifreeze must be added?

The answer is 6 L.

How much pure antifreeze should be added to 3 gallons of a 30 percent antifreeze solution to get 65 percent antifreeze?

Currently we have: 3 gallons of 30\% antifreeze ie 0.9 gallon of antifreeze and 2.1 gallons of solvent. Required solution is 65\% solution i.e average of 100\% and 30\% solution. So, we will have to add both the solution ( 100\% amd 30\%) in equal quantities. The answer is 3 gallons.

How much fluid should be drained and replaced with pure antifreeze so that the new mixture is 40\% antifreeze?

1 Expert Answer 6qts of antifreeze for every quart of mixture taken out and replaced with pure antifreeze. Because the mixture is at 40\% antifreeze and you want it to be 60\% that means you need the mixture to have 1.2qts more antifreeze in it: 3.6 – 2.4 = 1.2.

How many quarts of pure antifreeze must be added to 7 quarts of a 10 antifreeze solution to obtain a 20 antifreeze solution?

1 Expert Answer x = 0.875 quarts of pure 100\% antifreeze must be added to 7 quarts of 10\% antifreeze. The result will be 7.875 quarts of 20\% antifreeze.

What happens if you run pure antifreeze?

In fact, if pure antifreeze-coolant is used in a car’s cooling system, the system loses about 35 percent of the heat-transfer capabilities it otherwise would have when antifreeze is mixed with the proper amount of water. Running on pure antifreeze-coolant is pure folly and only will hasten your engine’s demise.

Is it OK to mix antifreeze coolant?

This is a mistake and can lead to expensive repairs. The two coolants should never be mixed together as they do not react well. When mixed together they can form a thick, jelly-like substance that can completely stop all coolant flow which can lead to overheating. The water pump may overheat and stop working.

Do the car need to be running when adding antifreeze?

Make sure your engine is off and cool, the vehicle is in Park or Neutral, and the parking brake is set. If your engine is cold, the coolant level should be up to the cold fill line. Loosen the reservoir cap just a little, then step back while the pressure releases.

How many gallons of antifreeze does a radiator need?

A typical automobile cooling and heating system can hold up to 3 gallons of antifreeze. Different systems require different solutions to be added to the water. Antifreeze, as well as rust and mineral inhibitors, are common additives.

How much fluid should be drained and replaced with pure antifreeze so that the new mixture is 60\% antifreeze?

2 Answers. 137quarts should be drained off and replaced with pure antifreeze.

How much water should be added to a gallon of pure antifreeze to obtain a solution that is antifreeze?

You need 3 gallons of water to make a solution that is 25\% antifreeze if you already have 1 gallon of pure antifreeze.
