1. Find the atomic weights of carbon and hydrogen:
* Carbon (C): 12.011 g/mol
* Hydrogen (H): 1.008 g/mol
2. Multiply the atomic weight of each element by its subscript in the molecular formula:
* Carbon: 60 atoms * 12.011 g/mol/atom = 720.66 g/mol
* Hydrogen: 122 atoms * 1.008 g/mol/atom = 123.00 g/mol
3. Add the results from step 2 to find the total molecular weight:
* 720.66 g/mol + 123.00 g/mol = 843.66 g/mol
Therefore, the molecular weight of C60H122 is 843.66 g/mol.
