You need to find the arrow key on your computer and use it. ==> or --> but not !.
Convert 75.0L CO2 to mols. mols = L/22.4 = ?
Use the coefficients in the balanced equation to convert mols CO2 to mols KO2.
Then g KO2 = mols x molar mass.
Consider the reaction
4KO2(s) + 2CO2(g) !
2K2CO3(s) + 3O2(g) .
How much KO2 is needed to react with 75.0 L
of carbon dioxide at STP?
