If you have 340 ml of 0.5 M NaBr solution what will the concentration be if you add 560 ml more water to it?

use dilution formula: M1*V1=M2*V2
(the 1's and 2's are subscript)
fill in the numbers and replace 'M2' with x because that is what you want to find out
so you get:
0.5*340=x*900
then, solve for x
you should get .19M of concentration

What could you do to affect the concentration of a nutrient solution?
you could put in less water and more fertilizer solution.
When more solvent is added to a solution what happens to the concentration?
The solution becomes more diluted and the concentration gets higher.
When comparing two solutions the solution with greater concentration is?
It often depends. The one with more solute has a higher concentration of solute than the other. In pertaining to osmosis, the hypotonic (or hypoosmotic) solution has less solute and more water over a semi-permeable membrane where the hyperotonic (or hyperosmotic) solution has more solute and less water over a semi-permeable membrane.
How onces of chemical per 384 oz of water?
It depends on the concentration of the solution. More info is needed to answer this question.
How can you change concentration?
To increase the concentration of a solution, you can decrease the amount of solvent by boiling off, or by evaporation, or you can simply add more solute. Conversely, to decrease the concentration, you can add more solvent.
Can the concentration of a substance change if it is an aqueous solution?
Yes. An aqueous solution means that at least one solute is dissolved in water. You can increase the concentration by adding more solute, or you can decrease the concentration by adding more water.
Is the concentration change after you add water to solution?
Adding more solute to a solution will increase its concentration. Adding more solvent will only dilute it. Think of salt water. The salt is the solute, and water is the solvent. Add salt and it becomes a more concentrated solution. Add more water, and it is more dilute. Simple and easy once you think it through.

What do isotonic hypotonic and hypertonic deal with?
A hypertonic solution is one containing more solute, a hypotonic solution contains more water, and an isotonic solution contains equal amounts of solute and water. Whether a solution is hypertonic, hypotonic, or isotonic can determine what happens to the cell. In a hypertonic solution, solute will diffuse into the cell down the concentration gradient. In a hypotonic solution, water will move into the cell by osmosis down a water potential gradient, and in an isotonic solution nothing will happen because the concentration and water potential are the same both inside and outside the cell.
What is isotonic hypotonic hypertonic solutions?
Isotonic is when the cell is the same concentration as the surrounding solution. Hypotonic is when the cell is more concentrated than the surrounding solution and water moves in. Hypertonic is when the cell is less concentrated than the surrounding solution and water moves out.
What is the solution that contains more water than what is located in the cells?
A hypertonic Solution. a solution that has a greater concentration of water than the cell content is hypotonic, meaning there is less concentration of water inside the cell, which results in an increase or an expansion of the cell.
What are the examples of hypotonic solution?
the concentration of water is more outside the cell is more than inside thecell
When more solvent is added to a solution what happens to the concentration?
The solution becomes more diluted and the concentration gets higher.
What can be done to sugar solution to make it more concentration?
You can either add more sugar or boil off some of the water.
What happens in a hypotonic solution?
A hypotonic solution is a solution that has less solute and more water than another solution. The concentration of total dissolved solutes is not equal on both sides, there will be net movement of water molecules into the cell.
What concentration of solutes is equal the concentration of solutes inside the cell?
when a concentration of something, usually water, is the same inside and outside a cell, it is called an isotonic solution. When there is more inside the cell or membrane, but less outside, the solution is hypotonic. when there is more on the outside , it is known as hypertonic. however, it depends what you are describing
Does a solution of baking soda and water have a lower pH that baking soda alone?
Pure baking soda does not have a pH. pH is the negative logarithm of the concentration of hydrogen ions in an aqueous solution (a solution where water is the solvent). But if you have baking soda, or any alkaline substance, in a higher concentration (i.e. more dissolved in the same amount of water) the pH will be higher, if it is in a lower concentration, the pH will be lower.
