 6·02 × 1022 oxygen molecules are present at –13°C in a 1500mL flask. What would be the pressure of the gas?

Solution

 Here comma space space straight V space equals space 1500 over 1000 straight L space equals 1.5 space straight L semicolon space space space space space space space space space straight T space equals space 273 space minus space 13 space equals space 260 space straight K space space space space space space space space space straight n space equals space fraction numerator 6.02 space cross times space 10 to the power of 22 over denominator 6.02 space cross times space 10 to the power of 23 end fraction space equals space 0.1
Applying ideal gas equation,    PV = nRT
Substituting the values, in the above equation, we have
  straight P space cross times space 1.5 space equals space 0.1 space cross times space 0.0821 space cross times space 260 therefore space space space space space space straight P space equals space 1.423 space bar
