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.
What if a semipermeable membrane has a 2 percent salt solution on one side a 15 percent salt solutionWhat will mostly occur?
Osmosis of water from a low concentration of salt to a high concentration
Explain how you prepare 15 percent NaCl?
1.Weigh 15 g ultrapure NaCl dried at 110 0C for 30 min. 2. Transfer NaCl in a clean 0,1 L volumetric flask. 3. Add 0,09 L demineralized water. 4. Put the flask in a thermostat and maintain 30 min at 20 0C. 5. Add demineralized water up to the mark. 6. Stir vigorously and transfer in a clean bottle with stopper. 7. Add a label with necessary information.
In which direction would osmosis occur if 15 percent sugar solution is separated from a 25 percent sugar solution?
It would flow toward the weaker solution. The intent of osmosis is to gain equilibrium, so the 15 percent solution would gain sugar content until, if you allowed the osmosis to go to completion, the two solutions had the same amount of sugar in them. "Going to completion" doesn't necessarily mean 20 percent concentration on both sides. If you were to make a gallon bag out of dialysis membrane, fill it with 15 percent solution and put a stirrer in it, then drop it into a 25,000-gallon reaction vessel full of 25 percent solution with a stirrer in it, you might wind up with 24.9999999999 percent sugar solution in both bags.
How many ounces of 15 percent percent alcohol must be mixed with 23 percent alcohol solution to make 100 ounces?
Let x be the ounces of 15% alcohol solution. The amount of alcohol in the 15% solution is 0.15x, and the amount of alcohol in the 23% solution is 0.23(100 - x). Setting up the equation 0.15x + 0.23(100 - x) = 0.15(100) solves for x, which is approximately 38.5 ounces of the 15% alcohol solution needed.
What is the mole fraction of 18 mol NaCl in a solution of 100 mol water?
The mole fraction of NaCl in the solution is calculated by dividing the moles of NaCl by the total moles of NaCl and water. In this case, the mole fraction of 18 mol NaCl in a solution of 100 mol water is 0.15 (18 mol NaCl / (18 mol NaCl + 100 mol water)).
How many liters of a 90 percent acid solution must be mixed with a 15 percent acid solution to get 600 L of a 80 percent solution?
Mixing 80 liters of 15% solution and 520 liters of 90% solution will give 600 liters of 80% solution.
How many grams of NaCl would be required to make 6M solution?
It depends on the final solution Volume you want to prepare. For 100ml of a 6M NaCL solution, you add 35.1g of NaCl to water until you reach 100ml. Dissolve and autoclave for 15 mins.

What ratio of hydrated lime copper sulphate is needed to make 15 liters of solution?
Depending on the desired concentration of the solution !
What does 15 M HNO3 mean?
15 M HNO3 indicates a solution of nitric acid with a concentration of 15 moles per liter. This solution is highly acidic and can be used for various chemical reactions and laboratory purposes. The M signifies molarity, a measurement of concentration.
What is the value of 15 percent of 600?
15% of 600 = 15% * 600 = 0.15 * 600 = 90
If you have a 300ml of a 15 percent hydrochloric acid solution in dilute the solution to 1000ml with sterile water what percent should appear on the label?
The concentration of the diluted solution will be 15(300/1000) = 4.5 %, if the percent is expressed on a weight/volume basis.
A semipermeable membrane has 2 percent salt solution on one side and a 15 percent salt solution on the other side what will most likely occur?
Osmosis of water from a low concentration of salt to a high concentration
A semipermeable membrane has 2 percent salt solution on one side and 15 percent salt solution on the other side. What will most likely occur?
Osmosis of water from a low concentration of salt to a high concentration
You mix 15g of sugar in enough water to make 1 L of solution The concentration of this solution is?
15 grams sugar per liter is the concentration, in terms of mass per volume. To express the concentration in molarity (assuming the sugar is sucrose): 15 g sucrose * (1 mole sucrose / 342 g sucrose) / 1 L = 0.0439 M aqueous sucrose
