Questionc. Calculate the molar mass of salicylic acid and acetyl salicylic acid (Aspirin).

Studdy Solution
Calculate the molar mass of acetylsalicylic acid ($\text{C}_9\text{H}_8\text{O}_4$).
- Calculate the total mass of carbon atoms: $ 9 \times 12.01 \, \text{g/mol} = 108.09 \, \text{g/mol} \]
- Calculate the total mass of hydrogen atoms: $ 8 \times 1.01 \, \text{g/mol} = 8.08 \, \text{g/mol} \]
- Calculate the total mass of oxygen atoms: $ 4 \times 16.00 \, \text{g/mol} = 64.00 \, \text{g/mol} \]
- Sum the masses to find the molar mass of acetylsalicylic acid: $ 108.09 \, \text{g/mol} + 8.08 \, \text{g/mol} + 64.00 \, \text{g/mol} = 180.17 \, \text{g/mol} \]
The molar mass of salicylic acid is $\boxed{138.13 \, \text{g/mol}}$ and the molar mass of acetylsalicylic acid is $\boxed{180.17 \, \text{g/mol}}$.
