Find the molar mass, M, for 1, 1, 2-trimethylcyclohexane: M = sum _iN_im_i Plan: • Write the chemical formula and gather atomic masses from the periodic table. • Determine values for N_i and m_i using these items. • Finally, compute the mass. Write the chemical formula: C_9H_18 Use the chemical formula to count the number of atoms, N_i, for each element:  | N_i  C (carbon) | 9  H (hydrogen) | 18 Look up the atomic mass, m_i, in g·mol^(-1) for each element in the periodic table:  | N_i | m_i/g·mol^(-1)  C (carbon) | 9 | 12.011  H (hydrogen) | 18 | 1.008 Multiply N_i by m_i to compute the mass for each element. Then sum those values to compute the molar mass, M: Answer: |   | | N_i | m_i/g·mol^(-1) | mass/g·mol^(-1)  C (carbon) | 9 | 12.011 | 9 × 12.011 = 108.099  H (hydrogen) | 18 | 1.008 | 18 × 1.008 = 18.144  M = 108.099 g/mol + 18.144 g/mol = 126.243 g/mol
