Result
![Find the molar mass, M, for 2, 4, 4-trimethyl-1-pentanol: 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)_3CCH_2CH(CH_3)CH_2OH Use the chemical formula, (CH_3)_3CCH_2CH(CH_3)CH_2OH, to count the number of atoms, N_i, for each element: | N_i C (carbon) | 8 H (hydrogen) | 18 O (oxygen) | 1 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) | 8 | 12.011 H (hydrogen) | 18 | 1.008 O (oxygen) | 1 | 15.999 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) | 8 | 12.011 | 8 × 12.011 = 96.088 H (hydrogen) | 18 | 1.008 | 18 × 1.008 = 18.144 O (oxygen) | 1 | 15.999 | 1 × 15.999 = 15.999 M = 96.088 g/mol + 18.144 g/mol + 15.999 g/mol = 130.231 g/mol](../image_source/b1b2225dcc1d8c3fe89d4460d73f316c.png)
