titanium trifluoride | molecular mass
Result
![Find the molecular mass, m, for titanium trifluoride: 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: TiF_3 Use the chemical formula to count the number of atoms, N_i, for each element: | N_i F (fluorine) | 3 Ti (titanium) | 1 Look up the atomic mass, m_i, in unified atomic mass units, u, for each element in the periodic table: | N_i | m_i/u F (fluorine) | 3 | 18.998403163 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 molecular mass, m: Answer: | | | N_i | m_i/u | mass/u F (fluorine) | 3 | 18.998403163 | 3 × 18.998403163 = 56.995209489 Ti (titanium) | 1 | 47.867 | 1 × 47.867 = 47.867 m = 56.995209489 u + 47.867 u = 104.862 u](../image_source/4b98af882483d7fef0cad2756882b2aa.png)
