hydrazine sulfate | molar mass
Result
![Find the molar mass, M, for hydrazine sulfate: 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_2NH_2·H_2SO_4 Use the chemical formula, NH_2NH_2·H_2SO_4, to count the number of atoms, N_i, for each element: | N_i H (hydrogen) | 6 N (nitrogen) | 2 O (oxygen) | 4 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) | 6 | 1.008 N (nitrogen) | 2 | 14.007 O (oxygen) | 4 | 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) | 6 | 1.008 | 6 × 1.008 = 6.048 N (nitrogen) | 2 | 14.007 | 2 × 14.007 = 28.014 O (oxygen) | 4 | 15.999 | 4 × 15.999 = 63.996 S (sulfur) | 1 | 32.06 | 1 × 32.06 = 32.06 M = 6.048 g/mol + 28.014 g/mol + 63.996 g/mol + 32.06 g/mol = 130.12 g/mol](../image_source/f9abcbffd5cdb997ae639945c8a4c373.png)
