  • The equation of state for of oxygen at a pressure <img alt="\mathrm{p}" src="https://entrancecorner

The equation of state for \mathrm{5g} of oxygen at a pressure \mathrm{p} and temperature 7, when occupying a volume \mathrm{V}, will be
 

Option: 1

\mathrm{pV = (5/32)RT}
 


Option: 2

\mathrm{pV = 5RT}
 


Option: 3

\mathrm{ pV = (5/2)RT}
 


Option: 4

\mathrm{ pV= (5/16)RT}


Answers (1)

best_answer

Number of moles, \mathrm{n=\frac{m}{\text { molecular weight }}=\frac{5}{32}}

So, from ideal gas equation,

\mathrm{ p V=n R T }

\mathrm{\Rightarrow \quad p V=\frac{5}{32} R T }

Hence option 1 is correct.
