D/days/845570/assessments/271356/varlants/271338) (ake/9 All conversion factors are equivalent to one. For example, the conversion factor given above is equivalent to one because the numerator (28.01 g CO) and denominator (1 mol CO) represent the same amount of CO. The "mol CO" unit is canceled, leaving an answer unit of grams. Question How do you solve problems in stoichiometry? Observe New question The first question is: "How many moles of carbon How many moles of carbon monoxide (CO) are required to react completely with 1.75 moles of iron (III) oxide (Fe203)? monoxide (CO) are required to react completely Fe,O with 1.75 moles of iron (III) oxide ( 23)?"

Activity B: Canceling Units Get the Gizmo Ready Check that the equation in the Gizmo is still: New equation Fe O, +3CO→2F +3CO, Fe203 (s) + 3CO (g) 2Fe (s) + 3CO2 (g) New question While solving problems in stoichiometry, it is useful to pay attention to the units of the answer. The process of comparing units is called dimensional analysis. A common technique involves using conversion factors to convert from one unit to another. Units that appear in the numerator and denominator of a fraction can be canceled out. For example, converting 2 moles of carbon monoxide to grams involves multiplying by a conversion factor: 28.01 g CO 2 mot CO x = 56.02 g CO 1 mot CO
