D-bornesitol | molecular mass
Result
Find the molecular mass, m, for D-bornesitol: 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_7H_14O_6 Use the chemical formula, C_7H_14O_6, to count the number of atoms, N_i, for each element: | N_i C (carbon) | 7 H (hydrogen) | 14 O (oxygen) | 6 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 C (carbon) | 7 | 12.011 H (hydrogen) | 14 | 1.008 O (oxygen) | 6 | 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 C (carbon) | 7 | 12.011 | 7 × 12.011 = 84.077 H (hydrogen) | 14 | 1.008 | 14 × 1.008 = 14.112 O (oxygen) | 6 | 15.999 | 6 × 15.999 = 95.994 m = 84.077 u + 14.112 u + 95.994 u = 194.183 u
