Find the molar mass, M, for ytterbium fluoride: 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: YbF_3 Use the chemical formula, YbF_3, to count the number of atoms, N_i, for each element:  | N_i  F (fluorine) | 3  Yb (ytterbium) | 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) | 3 | 18.998403163  Yb (ytterbium) | 1 | 173.045 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) | 3 | 18.998403163 | 3 × 18.998403163 = 56.995209489  Yb (ytterbium) | 1 | 173.045 | 1 × 173.045 = 173.045  M = 56.995209489 g/mol + 173.045 g/mol = 230.040 g/mol
