manganese(0) carbonyl | molar mass
Result
![Find the molar mass, M, for manganese(0) carbonyl: 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: Mn_2(CO)_10 Use the chemical formula to count the number of atoms, N_i, for each element: | N_i C (carbon) | 10 Mn (manganese) | 2 O (oxygen) | 10 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 Mn (manganese) | 2 | 54.938044 O (oxygen) | 10 | 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) | 10 | 12.011 | 10 × 12.011 = 120.110 Mn (manganese) | 2 | 54.938044 | 2 × 54.938044 = 109.876088 O (oxygen) | 10 | 15.999 | 10 × 15.999 = 159.990 M = 120.110 g/mol + 109.876088 g/mol + 159.990 g/mol = 389.976 g/mol](../image_source/2e9995c24497c7f4b87b8cff266a2179.png)
