monoclinic sulfur | molar mass
Result
![Find the molar mass, M, for monoclinic sulfur: 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: S_8 Use the chemical formula, S_8, to count the number of atoms, N_i, for each element: | N_i S (sulfur) | 8 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) S (sulfur) | 8 | 32.06 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) S (sulfur) | 8 | 32.06 | 8 × 32.06 = 256.48 M = 256.48 g/mol](../image_source/69371ad10f672ed0122e5846136d6745.png)
