To make a 500 dilution, add 1 part of the substance you are diluting to 499 parts of water. For example, if you have 1 mL of the substance, you would add 499 mL of water to make a total volume of 500 mL for the dilution.
When we say that a solution has a given molarity, it tells you how much of a given substance is dissolved into the solution. A 1.0 molar solution has one mole of a substance dissolved into one liter of water.
Dilute it when there isn't much solute in the solution. So there is a lot of solvent. Concentrated mean there is a lot of solute in the solution.
To make normal saline, you would need to add 9 grams of sodium chloride to one liter of water. This is equivalent to approximately 0.9% saline solution.
A liter of water weighs approximately 33.8 ounces.
To make 1 liter of 0.1 M NaCl solution, you will need 25 ml of the 4 M NaCl stock solution and 975 ml of water. This will give you the desired concentration of 0.1 M NaCl in a total volume of 1 liter.
To make a 500 dilution, add 1 part of the substance you are diluting to 499 parts of water. For example, if you have 1 mL of the substance, you would add 499 mL of water to make a total volume of 500 mL for the dilution.
At dilution always true:Volume*concentration = amount of solute (= constant, not changing)So 1 (litre) * 5 (%) => 5
To prepare a 1.5 M solution of HCl, you would need to dissolve 1.5 moles of HCl in enough water to make 1 liter of solution. To do this, measure out the correct amount of HCl, add it to a volumetric flask containing less than 1 liter of water, then add water to make a total volume of 1 liter while mixing the solution. Make sure to wear appropriate safety gear and handle HCl with caution as it is a strong acid.
When we say that a solution has a given molarity, it tells you how much of a given substance is dissolved into the solution. A 1.0 molar solution has one mole of a substance dissolved into one liter of water.
This is from the website linked to the left of this answer under Web Links:Solubility in water, g/100 ml at 20°C: 74.5Therefore, in 1 liter, 745.0 grams of CaCl2 will dissolve to make a saturated solution.
To dilute the copper chlorine solution from 100,000 ppm to 1 ppm, you would need to dilute it by a factor of 100,000. This means you would need 100,000 liters of water to dilute 1 liter of the original solution.
When we say that a solution has a given molarity, it tells you how much of a given substance is dissolved into the solution. A 1.0 molar solution has one mole of a substance dissolved into one liter of water.

30 liters of a 10 % solution of fertilizer has .1(30) = 3 liters of fertilizer 1 liter of 30% solution has .3 liter of fertilizer 10 liters of 30% solution has 3 liters of fertilizer so, the chemist needs 10 liters of the 30% solution and 20 liters of water to make 30 liters of a 10% solution.
Dilute it when there isn't much solute in the solution. So there is a lot of solvent. Concentrated mean there is a lot of solute in the solution.
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.
