Molar Mass of C9H8O4
How to work out the molar mass of C9H8O4
- Count the atoms of each element in C9H8O4: 9 C, 8 H and 4 O.
- Multiply each count by the element's atomic weight: 9 × 12.011 = 108.099; 8 × 1.008 = 8.064; 4 × 15.999 = 63.996.
- Add the results: 108.099 + 8.064 + 63.996 = 180.159 g/mol.
