Answer:
[tex]R=8.301\frac{L*kPa}{mol*K}[/tex]
Explanation:
Hello,
In this case, assuming oxygen as an ideal gas, it is described by:
[tex]PV=nRT[/tex]
Whereas the gas constant R is required, therefore, it is computed as shown below:
[tex]R=\frac{PV}{nT} =\frac{198kPa*12.5L}{1.00mol*(25+273.15)K} \\\\R=8.301\frac{L*kPa}{mol*K}[/tex]
Best regards.
