Here's how to calculate the molar mass of benzene (C6H6):

* Find the atomic masses:

* Carbon (C): 12.01 g/mol

* Hydrogen (H): 1.01 g/mol

* Multiply the atomic masses by the number of atoms in the formula:

* Carbon: 6 atoms * 12.01 g/mol = 72.06 g/mol

* Hydrogen: 6 atoms * 1.01 g/mol = 6.06 g/mol

* Add the results together:

* 72.06 g/mol + 6.06 g/mol = 78.12 g/mol

Therefore, the molar mass of benzene (C6H6) to the nearest gram is 78 g/mol.
