Answer 1

Answer:

18 percent

Explanation:

percentage of sugar=mass of salt/mass of solution

then divide it and multiply

25/450=18 percent

Answer 2

Explanation:

Answer:

10 %

• Explanation:
• Given mass of solute = 25 g

• and mass of solvent = 225 g

So mass of solution = mass of solvent + mass of solute

• Mass of solution = 25 g + 225 g = 250 g

$\begin{gathered}\sf We \ know \ mass \ \%= (\dfrac{mass \ of \ solute}{mass \ of \ solution}) \times100\\\\\\putting \ values \ here\\\\\\\ mass \ \%=(\dfrac{25}{250})\times100\\\\\\ mass \ \%=10\\\\\\Thus \ mass \ percentage \ of \ the \ solution \ is \ 10\%\end{gathered}$

Thus mass percentage of the solution is 10%
