Result
![Find the molar mass, M, for s-formylmycothiol: 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_18H_30N_2O_13S_1 Use the chemical formula to count the number of atoms, N_i, for each element: | N_i C (carbon) | 18 H (hydrogen) | 30 N (nitrogen) | 2 O (oxygen) | 13 S (sulfur) | 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) | 18 | 12.011 H (hydrogen) | 30 | 1.008 N (nitrogen) | 2 | 14.007 O (oxygen) | 13 | 15.999 S (sulfur) | 1 | 32.06 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) | 18 | 12.011 | 18 × 12.011 = 216.198 H (hydrogen) | 30 | 1.008 | 30 × 1.008 = 30.240 N (nitrogen) | 2 | 14.007 | 2 × 14.007 = 28.014 O (oxygen) | 13 | 15.999 | 13 × 15.999 = 207.987 S (sulfur) | 1 | 32.06 | 1 × 32.06 = 32.06 M = 216.198 g/mol + 30.240 g/mol + 28.014 g/mol + 207.987 g/mol + 32.06 g/mol = 514.50 g/mol](../image_source/28fcff6ba1d323cb6da134c5402e03c7.png)
