sulfamic acid | molar mass
Result
![Find the molar mass, M, for sulfamic acid: 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: NH_2SO_3H Use the chemical formula to count the number of atoms, N_i, for each element: | N_i H (hydrogen) | 3 N (nitrogen) | 1 O (oxygen) | 3 S (sulfur) | 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) H (hydrogen) | 3 | 1.008 N (nitrogen) | 1 | 14.007 O (oxygen) | 3 | 15.999 S (sulfur) | 1 | 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) H (hydrogen) | 3 | 1.008 | 3 × 1.008 = 3.024 N (nitrogen) | 1 | 14.007 | 1 × 14.007 = 14.007 O (oxygen) | 3 | 15.999 | 3 × 15.999 = 47.997 S (sulfur) | 1 | 32.06 | 1 × 32.06 = 32.06 M = 3.024 g/mol + 14.007 g/mol + 47.997 g/mol + 32.06 g/mol = 97.09 g/mol](../image_source/d61566e715b71aeae85d9e48a27d78aa.png)
