What is the difference of molar masses expressed in gram of two neighbouring members of a homologous series?

Step-by-step solution

A homologous series consists of compounds with the same functional group, where each successive member differs by a CH ₂ group. The molar mass of CH ₂ is calculated as 12 g/mol + 2 1 g/mol = 14 g/mol . The difference in molar masses is 14 g/mol.
