Result
![Find the molecular mass, m, for cesium orthovanadate: 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: Cs_3VO_4 Use the chemical formula to count the number of atoms, N_i, for each element: | N_i Cs (cesium) | 3 O (oxygen) | 4 V (vanadium) | 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 Cs (cesium) | 3 | 132.90545196 O (oxygen) | 4 | 15.999 V (vanadium) | 1 | 50.9415 Multiply N_i by m_i to compute the mass for each element.
