nickel carbonate | molar mass
Result
![Find the molar mass, M, for nickel carbonate: 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: NiCO_3 Use the chemical formula to count the number of atoms, N_i, for each element: | N_i C (carbon) | 1 Ni (nickel) | 1 O (oxygen) | 3 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) C (carbon) | 1 | 12.011 Ni (nickel) | 1 | 58.6934 O (oxygen) | 3 | 15.999 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) C (carbon) | 1 | 12.011 | 1 × 12.011 = 12.011 Ni (nickel) | 1 | 58.6934 | 1 × 58.6934 = 58.6934 O (oxygen) | 3 | 15.999 | 3 × 15.999 = 47.997 M = 12.011 g/mol + 58.6934 g/mol + 47.997 g/mol = 118.701 g/mol](../image_source/d5804f7f65e7023069e098882b05a143.png)
