WebJul 21, 2024 · The "non-whole number" empirical formula of the compound is Fe 1 O 1.5. Multiply each of the moles by the smallest whole number that will convert each into a whole number. Fe:O = 2 (1:1.5) = 2:3. Since the moles of O is still not a whole number, both moles can be multiplied by 2, while rounding to a whole number. WebJan 3, 2024 · Moles allow you to directly read weight from the periodic table (e.g., 1 mole of N₂ is 28 g or 1 mole of NaCl is 58.5 g). We can link the number of entities X in a specified sample – N(X), to the moles of X in the same sample – n(X), with the relation: n(X) = N(X)/NA. N(X) is dimensionless, and n(X) has the SI unit mole. batik lestari
