manganese titanate | molar mass
Result
![Find the molar mass, M, for manganese titanate: 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: MnTiO_3 Use the chemical formula to count the number of atoms, N_i, for each element: | N_i Mn (manganese) | 1 O (oxygen) | 3 Ti (titanium) | 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) Mn (manganese) | 1 | 54.938044 O (oxygen) | 3 | 15.999 Ti (titanium) | 1 | 47.867 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) Mn (manganese) | 1 | 54.938044 | 1 × 54.938044 = 54.938044 O (oxygen) | 3 | 15.999 | 3 × 15.999 = 47.997 Ti (titanium) | 1 | 47.867 | 1 × 47.867 = 47.867 M = 54.938044 g/mol + 47.997 g/mol + 47.867 g/mol = 150.802 g/mol](../image_source/322b0e4bbb1f3a4f549485f7a8ef7385.png)
