Answer:1.309 x 10^24 oxygen atoms

Explanation:

Molar mass of N2O4,=  2 x Molar mass of Nitrogen + 4 x Molar mass of Oxygen

= 2 x 14.01 + 4 x 16.0

= 92.02 g/mol

One mole of a substance is equal to 6.022 × 10²³ unit/ atoms/ molecules

In N2O4, there are 4  moles of Oxygen

if 92.02 g contains = 4 x 6.022 x 10 ^23 molecules

50.0 g wll contain=  (4 x 6.022 x 10 ^23  x 50)/ 92.02g

1.309 x 10^24 oxygen atoms

How many liters of O2 at 298 K and 1.00 bar are produced in 1.50 hr in an electrolytic cell operating at a current of 0.0200 A?
stellarik [79]

Answer: 0.0069L

Explanation:

2H2O(l) ---->O2(g) + 4H+(aq) + 4e-

no of moles= it/eF

NO of moles of O2 produced = (Current in Ampere x Time in second)/ (Faraday constant x Number of electrons required)

Moles of O2 produced = (0.02x (60 x 60X1.5 s)/(96485 x 4)

= 0.0002798 moles= 2.798x 10 ^-4moles

Using  ideal gas equation,

P V = n R T

Where, P is the pressure,

V is the volume,

n is the number of moles,

R is the gas constant, and T is the temperature

We have, 1 bar = 0.986923 atm

Substituting the values,

V = nRT/P = (2.798 x 10-4moles x 0.08205 L atm mol K x 298 K)/ 0.986923 atm = 0.0069L

Volume of O2 produced = 0.0069L
