Calculation of the Mass Percentages of Carbon, Hydrogen, and Oxygen in a Compound

To find the mass percentages of carbon, hydrogen, and oxygen in a compound, we need to use the formula and the given values.

Let's assume the compound consists of carbon (C), hydrogen (H), and oxygen (O). We are given that the mass percentages of carbon, hydrogen, and oxygen are 54.55%, 9.09%, and 36.36%, respectively.

To calculate the mass percentages, we can use the following formula:

Mass Percentage = (Mass of Element / Total Mass of Compound) x 100

Let's assign variables to the mass of carbon (C), hydrogen (H), and oxygen (O) in the compound:

- Mass of Carbon (C) = x grams - Mass of Hydrogen (H) = y grams - Mass of Oxygen (O) = z grams

According to the given percentages, we can write the following equations:

- x / (x + y + z) = 54.55% = 0.5455 - y / (x + y + z) = 9.09% = 0.0909 - z / (x + y + z) = 36.36% = 0.3636

Now, we can solve these equations to find the values of x, y, and z.

Let's start with the first equation:

x / (x + y + z) = 0.5455

Cross-multiplying, we get:

x = 0.5455 * (x + y + z)

Expanding the equation, we have:

x = 0.5455x + 0.5455y + 0.5455z

Rearranging the terms, we get:

0.4545x = 0.5455y + 0.5455z

Dividing both sides by 0.4545, we have:

x = (0.5455y + 0.5455z) / 0.4545

Similarly, we can solve the other two equations to find the values of y and z.

By substituting the given percentages into the equations, we can calculate the values of x, y, and z. However, since the snippet provided does not contain the necessary information to calculate the values, I am unable to provide the specific values for carbon, hydrogen, and oxygen in this compound.

If you have the specific values for the mass of the compound or any additional information, I would be happy to assist you further in calculating the mass percentages.
