tricyclohexyltin hydride | molar mass
Result
![Find the molar mass, M, for tricyclohexyltin hydride: 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_6H_11)_3SnH Use the chemical formula, (C_6H_11)_3SnH, to count the number of atoms, N_i, for each element: | N_i C (carbon) | 18 H (hydrogen) | 34 Sn (tin) | 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) | 18 | 12.011 H (hydrogen) | 34 | 1.008 Sn (tin) | 1 | 118.710 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) | 18 | 12.011 | 18 × 12.011 = 216.198 H (hydrogen) | 34 | 1.008 | 34 × 1.008 = 34.272 Sn (tin) | 1 | 118.710 | 1 × 118.710 = 118.710 M = 216.198 g/mol + 34.272 g/mol + 118.710 g/mol = 369.180 g/mol](../image_source/13f249155b18b123ec939547b53a407b.png)
