Find the molar mass, M, for cobalt phosphate: 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: Co_3(PO_4)_2 Use the chemical formula to count the number of atoms, N_i, for each element:  | N_i  Co (cobalt) | 3  O (oxygen) | 8  P (phosphorus) | 2 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)  Co (cobalt) | 3 | 58.933194  O (oxygen) | 8 | 15.999  P (phosphorus) | 2 | 30.973761998 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)  Co (cobalt) | 3 | 58.933194 | 3 × 58.933194 = 176.799582  O (oxygen) | 8 | 15.999 | 8 × 15.999 = 127.992  P (phosphorus) | 2 | 30.973761998 | 2 × 30.973761998 = 61.947523996  M = 176.799582 g/mol + 127.992 g/mol + 61.947523996 g/mol = 366.739 g/mol
