If 120 liters of an acid solution is 75 percent acid how much pure acid is there in the mixture?
90 litres
How much water must be mixed with concentrated hydrochloric acid to prapare 50cm3 of 6m hcl solution?
50mL minus the volume of 0.3 moles pure HCl is how much water is necessary. Be sure to add acid to water never water to acid.
How could you show that magnesium reacts with acid faster with acid than with pure water and what would you see?
Metallic magnesium will cause rapid evolution of hydrogen gas when contacted with an acid in water solution, but will cause gas evolution much more slowly if at all when in contact with pure water.
What is the conductivity of Hydrochloric acid?
That's a difficult question to answer, because "pure" hydrochloric acid is a gas at room temperature, and the conductivity of a solution of hydrochloric acid depends on the concentration.
How much pure acid should be mixed with 4 gallons of a 50 percent acid sollution in order to get an 80 percent acid solution?
Assuming that you mean that your pure acid is twice as concentrated as your 50% acid. Pretending your pure acid is at 1 mol/gallon and the 50% acid is 0.5 mol/gallon1 molgallon-1 * x gallons = x mol0.5 molgallon-1 * 4 gallons = 2 mol(x + 2) mol for (x+4) gallons = 0.8(x+2) mol / (x+4) gallons= 0.8 molgallon-1x + 2 = 0.8x + 3.20.2x = 1.2x = 6add 6 gallons of pure acid to the 4 gallons to make 10 gallons of 80% acid solution
How much pure acid is in 330 mL of a 18 percent acid solution?
18% of 330 = 59.4 So there are 59.3ml of pure acid in 330ml of 18% acid solution.
How much pure acid should be mixed with 5 gallons of 70 percent acid solution in order to get a 90 percent acid solution?
x=45
If 120 liters of an acid solution is 75 percent acid how much pure acid is there in the mixture?
90 litres
How much pure acid must be added to 12 ounces of a 40 percent acid solution in order to produce 60 percent acid solution?
6 ounces
How much pure acid should be mixed with 2 gallons of a 50 percent acid solution in order to get an 80 percent acid solution?
pH less than 7
How much pure acid should be mixed with 6 gallons of a 50 percent acid solution in order to get an 80 percent acid solution?
50% acid in a 6 gallon solution means that 3 gallons are acid. 9 gallons more acid will give you a total of 12 gallons of acid in a 15 gallon solution. 12 is 80% of 15.
A flask contains 300.0cm3 of a 0.500 acid solution How many moles of the pure acid must have dissolved?
All of the moles of pure acid will have dissolved in the flask.
How much water should be added to six liters of thirty percent acid solution to dilute twelve percent solution?
6 litres of 30% solution would contain 6*30/100 = 1.8 litres of pure acid.1.8 litres of pure acid, in a 12% solution means the total volume is 1.8*(100/12) = 15 litres in total. So you need to add 9 litres of pure water.6 litres of 30% solution would contain 6*30/100 = 1.8 litres of pure acid.1.8 litres of pure acid, in a 12% solution means the total volume is 1.8*(100/12) = 15 litres in total.

How much water should be added to 3 gallons of pure acid in order to obtain the 15 acid solution?
You need 17 gallons for a 15% volume/volume mixture.
2.943g of pure sulphuric acid H2S4 is dissolved in water to make 150.0 cm3 of solution What is the concentration of the solution?
The concentration of a solution is moles/volume. 2.943g of pure sulphuric acid H2S4 is approximately 15 moles, and 15/150 cm3 is 10.
