Question

what is the percent composition of the antibiotic tetracycline, which has the molecular formula of c22h24n2o8?

Answer 1

The percent composition of tetracycline (C22H24N2O8) can be calculated by dividing the mass of each element in the compound by the total mass of the compound and multiplying by 100. The percent composition is approximately 59.41% carbon, 5.43% hydrogen, 8.95% nitrogen, and 25.21% oxygen.

Step-by-step explanation:

The percent composition of a compound can be calculated by dividing the mass of each element in the compound by the total mass of the compound and then multiplying by 100. To find the percent composition of tetracycline (C22H24N2O8), we need to calculate the molar masses of carbon, hydrogen, nitrogen, and oxygen and then use those values to determine the percent composition.

The molar mass of carbon (C) is 12.01 g/mol, hydrogen (H) is 1.01 g/mol, nitrogen (N) is 14.01 g/mol, and oxygen (O) is 16.00 g/mol. To calculate the molar mass of tetracycline, we multiply the number of each element in the formula by its respective molar mass and add them together: (22 x 12.01) + (24 x 1.01) + (2 x 14.01) + (8 x 16.00) = 444.44 g/mol.

To find the percent composition of each element, we divide the molar mass of each element by the molar mass of the compound and multiply by 100. The percent composition of carbon in tetracycline is (22 x 12.01 / 444.44) x 100 = 59.41%. The percent composition of hydrogen is (24 x 1.01 / 444.44) x 100 = 5.43%. The percent composition of nitrogen is (2 x 14.01 / 444.44) x 100 = 8.95%. The percent composition of oxygen is (8 x 16.00 / 444.44) x 100 = 25.21%.

Answer 2

Tetracycline's percent composition is calculated as follows: Carbon (C): 60.92%, Hydrogen (H): 5.61%, Nitrogen (N): 6.44%, and Oxygen (O): 26.03%.

The percent composition is determined by dividing the molar mass of each element by the molar mass of the entire compound, then multiplying by 100.

In Tetracycline, the molecular formula C22H24N2O8 contributes to its structure, where carbon and oxygen are the major components, reflecting its complex and multifunctional nature as an antibiotic.

So, the percent composition of Tetracycline is 60.92% carbon, 5.61% hydrogen, 6.44% nitrogen, and 26.03% oxygen. This breakdown underscores the diverse elemental composition of Tetracycline, elucidating its molecular structure and providing insights into its pharmacological properties.
