Mix this 50% solution in equal quantities with water(?) to halve it's strength. So use 1 litre of the 50% solution and 1 litre of water of that's what you are diluting it with.

70 gallons of 20% solution contains 70*0.2 = 14 gallons of antifreeze. Suppose you need G gallons of the 80% antifreeze solution. This will contain 0.8*G gallons of antifreeze. Total volume of solution = G + 70 gallons Volume of antifreeze required in this solutions to make it a 70% solution is 0.7*(G + 70) = 0.7G + 49 gallons. Volume of antifreeze = 14 + 0.8G gallons So 0.7G + 49 = 14 + 0.8G 0.7G + 35 = 0.8G 35 = 0.1G 350 = G Answer: 350 gallons.

To make a liter of water, you would need two 500ml bottles of water. This is because 1 liter is equivalent to 1000ml. Therefore, two 500ml bottles combined would give you a total of 1000ml or 1 liter of water.
To make a 20% dextrose solution, you need to dilute the 70% dextrose solution with water. You need to use 178.57 ml of the 70% dextrose and 321.43 ml of water to make 500 ml of 20% dextrose solution.
50 Liters of the 60% solution.
To make a 10% NaOH solution, you would need 100 grams of NaOH per liter of water. So to make 1 liter, you would need 100 grams of NaOH.
684 ml
Mix this 50% solution in equal quantities with water(?) to halve it's strength. So use 1 litre of the 50% solution and 1 litre of water of that's what you are diluting it with.
(X gal)(0.15) = (1 gal)(0.025)0.15X = 0.025X = 0.17 gallons (4 quarts/1 gal.)(1 liter/1.06 quarts)(1000 ml/1 liter)= 642 milliliters============
The chemist will use 100 liters of the 80% acid solution and 100 liters of the 30% acid solution to make a 200-liter solution that is 62% acid. The amount of acid in the 80% solution will be 0.8 * 100 = 80 liters, and in the 30% solution, it will be 0.3 * 100 = 30 liters.
2%
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
Oh, what a lovely question! To prepare 500 ml of 40% dextrose, you'll need to mix 200 ml of 25% dextrose with 300 ml of 60% dextrose. By blending these two solutions together, you can create the desired 40% dextrose solution with care and precision. Just remember to mix gently and enjoy the process!
what percent of 63 is 9
To prepare a liter of 10% ammonia solution from the official strong solution: Calculate the volume of the concentrated ammonia solution needed using the dilution formula: C1V1 = C2V2. Measure the calculated volume of the concentrated ammonia solution and add distilled water to make a total volume of 1 liter. Mix thoroughly to ensure uniform distribution.
