E-caprolactone | molar mass
Result
![Find the molar mass, M, for E-caprolactone: 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_6H_10O_2 Use the chemical formula to count the number of atoms, N_i, for each element: | N_i C (carbon) | 6 H (hydrogen) | 10 O (oxygen) | 2 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) | 6 | 12.011 H (hydrogen) | 10 | 1.008 O (oxygen) | 2 | 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) | 6 | 12.011 | 6 × 12.011 = 72.066 H (hydrogen) | 10 | 1.008 | 10 × 1.008 = 10.080 O (oxygen) | 2 | 15.999 | 2 × 15.999 = 31.998 M = 72.066 g/mol + 10.080 g/mol + 31.998 g/mol = 114.144 g/mol](../image_source/65731023336cb61b9a07a0685e721971.png)
