To make a 50% solution of 100 ml, you would need to weigh 50g of the active ingredient. This is because in a 50% solution, half of the solution is the active ingredient and half is the solvent.
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
A saturated solution is a solution that holds the maximum amount of solute that can be dissolved in a solvent at a specific temperature and pressure.
The concentration of a solution refers to the amount of solute present in a given amount of solvent or solution. It can be expressed in various units such as molarity, molality, mass percent, or volume percent, depending on the context. Concentration is important in determining the properties and behavior of a solution.
A concentrated solution has a high amount of solute dissolved in a solvent, while a dilute solution has a low amount of solute dissolved in a solvent. The concentration of a solution is usually expressed in terms of mass or volume of solute per unit volume of solvent.

2%
percent concentration = (mass of solute/volume of solution) X 100 To solve for mass of solute, mass of solute = (percent concentration X volume of solution)/100 So, mass of solute = (10% X 100mL)/100 = 10g

If one solution has twice as much solvent, but has the same concentration then it also has twice as much insolvent.
Concentration is typically given with the volume of solution. This allows for a consistent measurement of how much solute is present in the entire solution, regardless of the volume of solvent used to make the solution.
