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}.
