Result
![Find the molar mass, M, for (+/-)-sodium camphorsulfonate: 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: C_10H_15NaO_4S Use the chemical formula, C_10H_15NaO_4S, to count the number of atoms, N_i, for each element: | N_i C (carbon) | 10 H (hydrogen) | 15 Na (sodium) | 1 O (oxygen) | 4 S (sulfur) | 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) C (carbon) | 10 | 12.011 H (hydrogen) | 15 | 1.008 Na (sodium) | 1 | 22.98976928 O (oxygen) | 4 | 15.999 S (sulfur) | 1 | 32.06 Multiply N_i by m_i to compute the mass for each element.
