Find the molecular mass, m, for lime: 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: CaO Use the chemical formula, CaO, to count the number of atoms, N_i, for each element:  | N_i  Ca (calcium) | 1  O (oxygen) | 1 Look up the atomic mass, m_i, in unified atomic mass units, u, for each element in the periodic table:  | N_i | m_i/u  Ca (calcium) | 1 | 40.078  O (oxygen) | 1 | 15.999 Multiply N_i by m_i to compute the mass for each element. Then sum those values to compute the molecular mass, m: Answer: |   | | N_i | m_i/u | mass/u  Ca (calcium) | 1 | 40.078 | 1 × 40.078 = 40.078  O (oxygen) | 1 | 15.999 | 1 × 15.999 = 15.999  m = 40.078 u + 15.999 u = 56.077 u
