Answer 3

Calculating Percentage of Salt in a Solution

To calculate the percentage of salt in a solution, we can use the formula:

Percentage = (Mass of salt / Total mass of solution) * 100

Given: - Mass of salt = 36 grams - Total mass of solution = 400 grams

Calculation

Using the given formula: Percentage = (36 / 400) * 100

Result

Percentage = 9%
