Find the molar mass, M, for sodium hexafluoroantimonate: 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: NaSbF_6 Use the chemical formula to count the number of atoms, N_i, for each element:  | N_i  F (fluorine) | 6  Na (sodium) | 1  Sb (antimony) | 1 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)  F (fluorine) | 6 | 18.998403163  Na (sodium) | 1 | 22.98976928  Sb (antimony) | 1 | 121.760 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)  F (fluorine) | 6 | 18.998403163 | 6 × 18.998403163 = 113.990418978  Na (sodium) | 1 | 22.98976928 | 1 × 22.98976928 = 22.98976928  Sb (antimony) | 1 | 121.760 | 1 × 121.760 = 121.760  M = 113.990418978 g/mol + 22.98976928 g/mol + 121.760 g/mol = 258.740 g/mol
