Find the molar mass, M, for 2, 4-dimethylstyrene: 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: (CH_3)_2C_6H_3CH=CH_2 Use the chemical formula, (CH_3)_2C_6H_3CH=CH_2, to count the number of atoms, N_i, for each element:  | N_i  C (carbon) | 10  H (hydrogen) | 12 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) | 10 | 12.011  H (hydrogen) | 12 | 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) | 10 | 12.011 | 10 × 12.011 = 120.110  H (hydrogen) | 12 | 1.008 | 12 × 1.008 = 12.096  M = 120.110 g/mol + 12.096 g/mol = 132.206 g/mol
