lithium titanate | molar mass
Result
![Find the molar mass, M, for lithium 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: Li_2O_3Ti Use the chemical formula to count the number of atoms, N_i, for each element: | N_i Li (lithium) | 2 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) Li (lithium) | 2 | 6.94 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) Li (lithium) | 2 | 6.94 | 2 × 6.94 = 13.88 O (oxygen) | 3 | 15.999 | 3 × 15.999 = 47.997 Ti (titanium) | 1 | 47.867 | 1 × 47.867 = 47.867 M = 13.88 g/mol + 47.997 g/mol + 47.867 g/mol = 109.74 g/mol](../image_source/43181bff431a1fa789912195e57018de.png)
