Interpreting reaction equations in terms of moles In terms of the reaction equation above and starting with 5.8 mol of CO, a. how many moles of O2 are needed to convert all of the CO to CO2? b. how many moles of CO2 are obtained when all of the CO is converted to CO2?

Question

Interpreting reaction equations in terms of moles
In terms of the reaction equation above and starting with 5.8 mol of CO,
a. how many moles of [latex] O_{2} [/latex] are needed to convert all of the CO to [latex] CO_{2} [/latex]?
b. how many moles of CO 2 are obtained when all of the CO is converted to [latex] CO_{2} [/latex]?
Strategy
In part a, you are asked to convert from moles of CO into moles of [latex] O_{2} [/latex]. The conversion factor to use is based on the relationship that 2 mol of CO require 1 mol of [latex] O_{2} [/latex] to completely react (see the balanced equation). A similar approach is used to solve part b.

Accepted Answer

a. Convert from moles of CO to moles of [latex] O_{2} [/latex]

[latex] 5.8 \sout{molCO} imes \frac{1 mol O_{2}}{2 \sout{molCO}} = 2.9 mol O_{2} [/latex]

b. Convert from moles of CO to moles of [latex] CO_{2} [/latex]

[latex] 5.8 \sout{molCO} imes \frac{2 mol CO_{2}}{2 \sout{molCO}} = 5.8 mol CO_{2} [/latex]
