Question

Select the correct answer.

Answer 1

Answer:

      $\large\boxed{\large\boxed{820liter}}$

Explanation:

Use the ideal gas equation:

    $pV=nRT$

Where:

• p is the pressure: 202.6kPa
• n is the number of moles: 0.050 mol
• T is the temperatue in absolute scale: 400K
• R is the universal constant for ideal gases: 8.314 L-kPa / K-mol
• V is the volume

Substitute and solve for V:

       $202.6kPa\times V=0.050mol\times 8.314L\cdot kPa/k\cdot mol\times 400K\\ \\ \\ V=0.8207m^3$

Convert to liters:

      $V=0.8207m^3\times 1,000liter/m^3=820liters$

The answer is rounded to two significant figures.
