A) \[6.23\times {{10}^{26}}\]
B) \[0.33\times {{10}^{28}}\]
C) \[3.3\times {{10}^{21}}\]
D) none of these
Correct Answer: C
Solution :
From ideal gas equation \[PV=nkT\] \[\Rightarrow \] \[n=\frac{PV}{kT}\] Putting \[P=13.8\,Pa,\,V=1\,{{m}^{3}}\] \[k=1.38\times {{10}^{-23}}J{{K}^{-1}},T=300K\] \[\therefore \] \[n=\frac{13.8\times 1}{1.38\times {{10}^{-23}}\times 300}\] \[n=3.3\times {{10}^{21}}\]You need to login to perform this action.
