How many liters of 9 percent salt solution and 18 percent salt solution are needed to make 18 liters of 10 percent salt solution?
A. 16 of 18 percent and 2 of 9 percent b. 14 of 18 percent and 4 of 9 percent c. 16 of 9 percent and 2 of 18 percent d. 14 of 9 percent and 4 of 18 percent
Why does a potato not gain or lose mass in a 4 percent concentrated salt solution?
Because the environment is Isotonic (having the same or equal osmotic pressure).
How much pure acid should be mixed with 2 gallons of a 70 percent acid solution in order to get a 90 percent acid solution?
Set up. .70(2 gal) + X = .90(X + 2 gal) distribute 1.4 + X = .90X + 1.8 X = .90X + .4 .1X = .4 X = 4
How much water added to convert a 10 percent solution to 02 percent solution?
add 4 parts water per part solution
How many ounces of a ten percent alcohol solution must be mixed with 6 ounces of a fifteen percent alcohol solution to make a thirteen percent alcohol solution?
4 ounces
Is a 2 percent salt solution hypertonic or hypotonic to a 4 percent salt solution?
A 2% salt solution is hypotonic compared to a 4% salt solution because it has a lower concentration of salt. In osmosis, water flows from hypotonic to hypertonic solutions, so in this case, water would flow from the 2% solution to the 4% solution to try to equalize the concentrations.
How many liters of 9 percent salt solution and 18 percent salt solution are needed to make 18 liters of 10 percent salt solution?
A. 16 of 18 percent and 2 of 9 percent b. 14 of 18 percent and 4 of 9 percent c. 16 of 9 percent and 2 of 18 percent d. 14 of 9 percent and 4 of 18 percent
A chemist needs 4 liters of a 50 percent salt solution All she has available is a 20 percent salt solution and a 70 percent salt solution How much of each of the two solutions should she mix to obtain?
To achieve a 50% salt solution with 4 liters total volume, the chemist needs 2 liters of each of the 20% and 70% solutions. This is because the resulting solution will be a combination of the two strengths in equal amounts, leading to an overall concentration of 50%.
What are the release dates for Beggars and Choosers - 1999 Fifty Three Percent Solution 2-2?
Beggars and Choosers - 1999 Fifty Three Percent Solution 2-2 was released on: USA: 4 July 2000
Why does a potato not gain or lose mass in a 4 percent concentrated salt solution?
Because the environment is Isotonic (having the same or equal osmotic pressure).
How many grams of salt must be dissolved in water to make two liters of a two mole salt solution?
To make a two mole salt solution in two liters of water, you'll need 4 moles of salt (2 moles/L * 2 L = 4 moles). The molar mass of salt (NaCl) is approximately 58.44 g/mol, so 4 moles would be 233.76 grams (4 moles * 58.44 g/mol = 233.76 g).
How do you get rock salt from rocks?
1. Grinding of the rock salt. 2. Dissolving of the rock salt in water. 3. Filtering of the solution. 4. Repeated processes of crystallization/recrystallization.
What percantage of salt in oceans?
4 percent
What are the principal end uses for salt?
chemicals (45 percent), road de-icing/ice control salt (31 percent), salt sold to distributors (8 percent), industrial uses (8 percent), agricultural salt (6 percent), food (including table salt, 4 percent)

How much pure acid should be mixed with 2 gallons of a 70 percent acid solution in order to get a 90 percent acid solution?
Set up. .70(2 gal) + X = .90(X + 2 gal) distribute 1.4 + X = .90X + 1.8 X = .90X + .4 .1X = .4 X = 4
