Find the molar mass, M, for periodic acid: 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: H_5IO_6 Use the chemical formula to count the number of atoms, N_i, for each element:  | N_i  H (hydrogen) | 5  I (iodine) | 1  O (oxygen) | 6 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)  H (hydrogen) | 5 | 1.008  I (iodine) | 1 | 126.90447  O (oxygen) | 6 | 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)  H (hydrogen) | 5 | 1.008 | 5 × 1.008 = 5.040  I (iodine) | 1 | 126.90447 | 1 × 126.90447 = 126.90447  O (oxygen) | 6 | 15.999 | 6 × 15.999 = 95.994  M = 5.040 g/mol + 126.90447 g/mol + 95.994 g/mol = 227.938 g/mol
