Result
![Find the molar mass, M, for 1, 2, 3, 4-tetrahydroisoquinoline: 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: C_9H_11N Use the chemical formula, C_9H_11N, to count the number of atoms, N_i, for each element: | N_i C (carbon) | 9 H (hydrogen) | 11 N (nitrogen) | 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) C (carbon) | 9 | 12.011 H (hydrogen) | 11 | 1.008 N (nitrogen) | 1 | 14.007 Multiply N_i by m_i to compute the mass for each element.
