NaClO3is used in spacecraft to produceO2. The daily consumption of pureO2by a person is 492 L at 1 atm, 300 K. How much amount ofNaClO3(in grams) is required to produceO2for the daily consumption of a person at 1 atm, 300 K?

NaClO3s+Fes→O2g+NaCls+FeOs  R=0.082 L atm mol–1K–1

Options:

Answer:
C
Solution:

Moles ofNaClO3=moles ofO2
moles ofO2=PVRT=1×4920.082×300=20moles
As molecular mass ofNaClO3=106.5
NaClO3=20×106.5=2130 g
