The amount of water that must be evaporate from 500 grams of a 10% salt solution to obtain a 15% salt solution is: 166.67 g
To solve this problem, the formula and the procedure that we have to use is:
c1 * m1 = c2 * m2
Where:
- c1= concentration of the concentrated solution
- m1 = mass of the concentrated solution
- c2 = concentration of the diluted solution
- m2 = mass of the diluted solution
Information about the problem:
- c1 = 10%
- m1=500 g
- c2 = 15%
- m2= m1 - x
- Amount of water evaporate = x
Applying the dissolution of concentrations formula, we get:
c1 * m1 = c2 * m2
10% * 500g = 15% * (500 g - x)
0.10 * 500g = 0.15*(500g - x)
50 g = 75g - 0.15x
Isolating the (x) variable, we have:
0.15x = 75g - 50 g
0.15x = 25g
x = 25g / 0.15
x = 166.67 g
What is a solution?
In chemistry a solution is known as a homogeneous mixture of two or more components called:
- Solvent: it usually is in a major amount than the solute
- Solute: it usually is in less amount than the solvent
