Solution

The correct option is A $0.024 g$
The balanced reaction is as follows:
$4 K O_{2} + 2 H_{2} O + 4 C O_{2} \to 4 K H C O_{3} + 3 O_{2}$

$4$ moles of $K O_{2}$ produces $3 \times 32$ g of $O_{2}$ .
Therefore, $O_{2}$ produced by $10^{- 3}$ mol of $C O_{2} = \frac{3 \times 32 \times 10^{- 3}}{4} = 0.024 g$ .

Option A is correct.

If one breath exhales 1×10−3 mol of CO2, how much O2 will be produced by KO2 during one breath exhalation?

The correct option is A 0.024gThe balanced reaction is as follows:4KO2+2H2O+4CO2→4KHCO3+3O24 moles of KO2 produces 3×32 g of O2.Therefore, O2 produced by 10−3 mol of CO2=3×32×10−34=0.024 g.Option A is correct.
