What volume does 1.70 ×10–3 mol of chlorine gas occupy if its temperature is 20.2 °C and its pressure is 795 mm Hg?

Respuesta :

Explanation:

The given data is as follows.

     No. of moles = [tex]1.70 \times 10^{-3}[/tex],           V = ?

     T = 20.2 + 273 K = 293.2 K,             P = [tex]\frac{795 mm Hg}{760.0 mm Hg/atm}[/tex] = 1.046 atm,                      R = [tex]0.0821 L atm K^{-1}mol ^{-1}[/tex]

Calculate the volume using ideal gas equation as follows.

                                    P V = n R T

    [tex]1.046 atm \times V = 1.70 \times 10^{-3} \times 0.0821 L atm K^{-1}mol ^{-1} \times 293.2 K[/tex]

                                  V = [tex]\frac{1.70 \times 10^{-3} \times 0.0821 L atm K^{-1}mol ^{-1} \times 293.2 K}{1.046 atm}[/tex]

                                   = [tex]\frac{40.921 L atm}{1.046 atm}[/tex]

                                   = [tex]39.122 \times 10^{-3}[/tex] L

Thus, we can conclude that volume of the gas is [tex]39.122 \times 10^{-3}[/tex] L.
