organidin | molar mass
Result
![Find the molar mass, M, for organidin: 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_6H_11IO_3 Use the chemical formula, C_6H_11IO_3, to count the number of atoms, N_i, for each element: | N_i C (carbon) | 6 H (hydrogen) | 11 I (iodine) | 1 O (oxygen) | 3 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) | 6 | 12.011 H (hydrogen) | 11 | 1.008 I (iodine) | 1 | 126.90447 O (oxygen) | 3 | 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) | 6 | 12.011 | 6 × 12.011 = 72.066 H (hydrogen) | 11 | 1.008 | 11 × 1.008 = 11.088 I (iodine) | 1 | 126.90447 | 1 × 126.90447 = 126.90447 O (oxygen) | 3 | 15.999 | 3 × 15.999 = 47.997 M = 72.066 g/mol + 11.088 g/mol + 126.90447 g/mol + 47.997 g/mol = 258.055 g/mol](../image_source/f359dbc9778e455220bb771bf65cc770.png)
