silver iodate | molar mass
Result
![Find the molar mass, M, for silver iodate: 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: AgIO_3 Use the chemical formula to count the number of atoms, N_i, for each element: | N_i Ag (silver) | 1 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) Ag (silver) | 1 | 107.8682 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) Ag (silver) | 1 | 107.8682 | 1 × 107.8682 = 107.8682 I (iodine) | 1 | 126.90447 | 1 × 126.90447 = 126.90447 O (oxygen) | 3 | 15.999 | 3 × 15.999 = 47.997 M = 107.8682 g/mol + 126.90447 g/mol + 47.997 g/mol = 282.770 g/mol](../image_source/a9d5f3c346ddb775d6f0e6c0e8d45ef0.png)
