actually it is 5% of 100 is 5
Therefore, 5% of 500 is 5 x 5 = 25g
Taking into account the definition of weight / volume percentage (% w/v), the mass of sucrose would be 25 grams.
In first place, it is necessary to know that a solution is a mixture of two or more components, perfectly homogeneous since each component is intimately mixed with the other, in such a way that they lose their individual characteristics.
The latter means that the constituents are indistinguishable and the whole is presented in a single well-defined phase.
In a solution, a solute is that component that is found in the least amount and is the one that dissolves, while the solvent is that component that is in the greatest amount and is the medium that dissolves the solute.
The weight / volume percentage (% w/v) expresses the grams of solute that are dissolved in 100 mL of solution. The expression for its calculation is:
[tex]weight/volume percentage=\frac{mass solute}{volume solution}x100[/tex]
In this case, you know that:
Replacing:
[tex]5=\frac{mass solute}{500 mL} x100[/tex]
Solving:
[tex]mass solute=\frac{5x500 mL}{100}[/tex]
mass solute= 25 grams
In summary, the mass of sucrose would be 25 grams.
