Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Identify the Chemical Formula of Potassium Hydrogen Phthalate (KHP)
The chemical formula for KHP is $$\mathrm{KC}_8\mathrm{H}_5\mathrm{O}_4
Step 3:: Determine the Atomic Masses of Each Element
- Oxygen (O): $$m_{O} = 15.9994 \mathrm{~g/mol}
- Carbon (C): m_{C} = 12.0107 \mathrm{~g/mol}
Step 4:: Calculate the Molar Mass by Summing Atomic Masses
- Oxygen: $$4 \times 15.9994 = 63.9976 \mathrm{~g/mol}
- Carbon: 8 \times 12.0107 = 96.0856 \mathrm{~g/mol}
Step 5:: Sum the Individual Atomic Masses
\mathrm{Molar~Mass} = 39.0983 + 96.0856 + 5.0397 + 63.9976 = 204.2212 \mathrm{~g/mol}
Final Answer
The molar mass of Potassium Hydrogen Phthalate (KHP) is 204.2212 \mathrm{~g/mol}.
