Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Identify the Elements
The molecular formula for acetylsalicylic acid is $$\mathrm{C}_{9}\mathrm{H}_{8}\mathrm{O}_{4}$$, which contains:
- Carbon (C) - Hydrogen (H) - Oxygen (O)
Step 3:: Look Up Atomic Masses
- Oxygen (O): $$16.00 \mathrm{g/mol}
I'll use the periodic table to find the atomic masses:
Step 4:: Calculate Mass for Each Element
- Oxygen: $$4 \times 16.00 = 64.00 \mathrm{g/mol}
- Hydrogen: 8 \times 1.008 = 8.064 \mathrm{g/mol}
Step 5:: Sum the Masses
108.09 + 8.064 + 64.00 = 180.154 \mathrm{g/mol}
Final Answer
The molar mass of acetylsalicylic acid is 180.154 \mathrm{g/mol}.
