Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Identify the chemical formula
The chemical formula for citric acid is $$\mathrm{H}_{3}\mathrm{C}_{6}\mathrm{H}_{5}\mathrm{O}_{7}
Step 3:: Determine the atomic masses
- Oxygen (O): $$16.00 \mathrm{g/mol}
- Carbon (C): 12.01 \mathrm{g/mol}
Step 4:: Calculate the number of atoms of each element
- Oxygen (O): $$7 \mathrm{~atoms}
- Carbon (C): 6 \mathrm{~atoms}
Step 5:: Calculate the mass contribution of each element
- Oxygen: $$7 \times 16.00 = 112.00 \mathrm{g/mol}
- Carbon: 6 \times 12.01 = 72.06 \mathrm{g/mol}
Step 6:: Sum the individual masses
8.064 + 72.06 + 112.00 = 192.124 \mathrm{g/mol}
Final Answer
The molar mass of citric acid (\mathrm{H}_{3}\mathrm{C}_{6}\mathrm{H}_{5}\mathrm{O}_{7}) is 192.124 \mathrm{g/mol}.
