Calculating the Mass Percentages of Chemical Elements in Al(OH)3

To calculate the mass percentages of the chemical elements in the compound Al(OH)3, we can use the information provided in the search results.

The compound Al(OH)3 consists of the elements aluminum (Al), oxygen (O), and hydrogen (H).

According to the information from source the percentages of these elements in Al(OH)3 are as follows: - Aluminum (Al): 51.28% - Oxygen (O): 27.35% - Hydrogen (H): 9.40%

This information allows us to calculate the mass percentages of the chemical elements in Al(OH)3.

Calculation:

- Aluminum (Al): 51.28% - Oxygen (O): 27.35% - Hydrogen (H): 9.40%

To calculate the mass percentages of the chemical elements, we can use the following formula: - Mass Percentage = (Mass of Element / Total Mass of Compound) * 100

Using this formula, we can calculate the mass percentages of the chemical elements in Al(OH)3.

- Aluminum (Al): (51.28 / 100) * 100 = 51.28% - Oxygen (O): (27.35 / 100) * 100 = 27.35% - Hydrogen (H): (9.40 / 100) * 100 = 9.40%

Therefore, the mass percentages of the chemical elements in Al(OH)3 are: - Aluminum (Al): 51.28% - Oxygen (O): 27.35% - Hydrogen (H): 9.40%

This calculation is based on the provided information and demonstrates the mass percentages of the chemical elements in the compound Al(OH)3.
