Approach:
- Find the molar mass of carbon in cortisone
- Calculate the percentage of carbon in cortisone
Calculation:
- Number of carbon atoms in cortisone = 21
- Molecular weight of cortisone = 360.4 g/mol
- Molar mass of carbon = 12 g/mol
- Total molar mass of carbon in cortisone = 21 x 12 g/mol = 252 g/mol
- Percentage of carbon in cortisone = (252 g/mol ÷ 360.4 g/mol) x 100% = 69.9%
Answer:
- The approximate percentage of carbon in cortisone is 70%.
- Option (3) is the correct answer.
Explanation:
- Cortisone is a molecular substance containing 21 atoms of carbon per molecule.
- The molecular weight of cortisone is 360.4.
- To find the percentage of carbon in cortisone, we need to calculate the molar mass of carbon in cortisone and divide it by the molecular weight of cortisone.
- The molar mass of carbon in cortisone is calculated by multiplying the number of carbon atoms by the molar mass of carbon.
- The percentage of carbon in cortisone is calculated by dividing the molar mass of carbon in cortisone by the molecular weight of cortisone and multiplying by 100%.
- The approximate percentage of carbon in cortisone is 70%.
