Answer:

Mass of sucrose = 81 g

Explanation:

Given data:

Mass of solute = ?

Mass of water = 540 g

% of solution = 15.0%

Solution:

Formula:

% age of solution = mass of sucrose / mass of water × 100

Now we will put the values.

15 = mass of sucrose / 540 g× 100

15 /100 = mass of sucrose / 540 g

0.15 = mass of sucrose / 540 g

Mass of sucrose = 0.15 × 540 g

Mass of sucrose = 81 g
