Find the molar mass, M, for indium hydroxide: 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: In(OH)_3 Use the chemical formula, In(OH)_3, to count the number of atoms, N_i, for each element:  | N_i  H (hydrogen) | 3  In (indium) | 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)  H (hydrogen) | 3 | 1.008  In (indium) | 1 | 114.818  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)  H (hydrogen) | 3 | 1.008 | 3 × 1.008 = 3.024  In (indium) | 1 | 114.818 | 1 × 114.818 = 114.818  O (oxygen) | 3 | 15.999 | 3 × 15.999 = 47.997  M = 3.024 g/mol + 114.818 g/mol + 47.997 g/mol = 165.839 g/mol
