Question

9×10²² atoms of Ar and n moles of O2 are kept in a vessel of capacity 5L at 1 atm and 27C. If all the O2 is converted to O3 in vessel, total number of molecules in vessel changes but number of atoms remain constant. Explain.

Answer 2

Answer :

Step by step explanation :

Moles of Ar gas taken are

$n = \frac{9 \times {10}^{22} }{6 \times {10}^{23} }$

= 0.15 moles

The Ideal Gas Equation states that

$PV = nRT$

Substituting the given values, we get

$1(5) = (n + 0.15)(0.082)(300)$

R is Universal gas constant (0.082 l atm/mol k)

300 K is 27° C

Solving this equation we get

n = 0.05 mol

Thus the no. of Molecules of O2
