Question

Ok so we have a reaction
4 KO2 + 2 CO2 ---> 2 K2CO3 + 3 O2
.425mol KO2 and .319 mol O2
and the question is How many grams of KO2 are needed to form 8.0 g of O2

Answer 1

@Preetha

Answer 2

@JFraser @msamman10

Answer 3

\(KO_2\) isn't a proper formula, it should be \(K_2O\).

Start with the mass of O2 needed, then convert that into moles, then use the mole ratio from the balanced equation to find the moles of \(K_2O\) needed to produce that amount

Answer 4

the question says KO2

Answer 5

potassium superoxide does exist. but I am not sure it's applications.

Answer 6

i forgot about superoxides, but the process is exactly the same

Answer 7

Ok thanks
