Result
![Find the molar mass, M, for iodoacetonitrile: 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: ICH_2CN Use the chemical formula to count the number of atoms, N_i, for each element: | N_i C (carbon) | 2 H (hydrogen) | 2 I (iodine) | 1 N (nitrogen) | 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) | 2 | 12.011 H (hydrogen) | 2 | 1.008 I (iodine) | 1 | 126.90447 N (nitrogen) | 1 | 14.007 Multiply N_i by m_i to compute the mass for each element.
