How many moles are in 23.0 g of iron ii oxide
Web8 sep. 2011 · Best Answer. Copy. 1 mole Fe = 55.845g Fe. 1 mole Fe = 6.022 x 1023 atoms Fe. 23.0g Fe x (1 mole Fe/55.845g Fe) x (6.022 x 1023 atoms Fe/1 mole Fe) = … WebThe answer is that relates to the number of moles of the substance as indicated by its coefficient in the balanced chemical reaction. Thus, 2 mol of H 2 are related to −570 kJ, while 1 mol of O 2 is related to −570 kJ. This is why the unit on the energy change is kJ, not kJ/mol. For example, consider the following thermochemical equation:
