To calculate the molar mass of ethyl acetate, we need to add up the atomic masses of each atom present in the compound. Ethyl acetate has the molecular formula CH3COOCH2CH3.

C: 6 atoms x 12.01 g/mol = 72.06 g/mol

H: 8 atoms x 1.008 g/mol = 8.064 g/mol

O: 2 atoms x 16.00 g/mol = 32.00 g/mol

Total molar mass = 72.06 g/mol + 8.064 g/mol + 32.00 g/mol = 112.124 g/mol

Therefore, the molar mass of ethyl acetate is 112.124 g/mol.
