Input interpretation
acetic acid | atom count
Result
Determine the number of atoms in: acetic acid (CH_3CO_2H) Plan: • Use the summation: N_atoms = sum_i N_i. • Determine the values of N_i. • Compute the number of atoms. Use the chemical formula, CH_3CO_2H, to count the number of atoms, N_i, for each element: | N_i C | 2 H | 4 O | 2 Sum the N_i terms to compute the number of atoms, N_atoms: Answer: | | N_atoms = 2 + 4 + 2 = 8
