Find the molar mass, M, for scandium chloride: 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: ScCl_3 Use the chemical formula to count the number of atoms, N_i, for each element:  | N_i  Cl (chlorine) | 3  Sc (scandium) | 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)  Cl (chlorine) | 3 | 35.45  Sc (scandium) | 1 | 44.955908 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)  Cl (chlorine) | 3 | 35.45 | 3 × 35.45 = 106.35  Sc (scandium) | 1 | 44.955908 | 1 × 44.955908 = 44.955908  M = 106.35 g/mol + 44.955908 g/mol = 151.31 g/mol
