Find the molar mass, M, for sodium chloroacetate: 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: ClCH_2COONa Use the chemical formula, ClCH_2COONa, to count the number of atoms, N_i, for each element:  | N_i  C (carbon) | 2  Cl (chlorine) | 1  H (hydrogen) | 2  Na (sodium) | 1  O (oxygen) | 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)  C (carbon) | 2 | 12.011  Cl (chlorine) | 1 | 35.45  H (hydrogen) | 2 | 1.008  Na (sodium) | 1 | 22.98976928  O (oxygen) | 2 | 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)  C (carbon) | 2 | 12.011 | 2 × 12.011 = 24.022  Cl (chlorine) | 1 | 35.45 | 1 × 35.45 = 35.45  H (hydrogen) | 2 | 1.008 | 2 × 1.008 = 2.016  Na (sodium) | 1 | 22.98976928 | 1 × 22.98976928 = 22.98976928  O (oxygen) | 2 | 15.999 | 2 × 15.999 = 31.998  M = 24.022 g/mol + 35.45 g/mol + 2.016 g/mol + 22.98976928 g/mol + 31.998 g/mol = 116.48 g/mol
