A container of gas has a volume of 3.5 L and a pressure of 0.8 atm. Assuming the temperature remains constant, what volume of ga
vovikov84 [41]
<h3>Answer:</h3>

5.6 L

<h3>Explanation:</h3>

We are given;

  • Initial volume, V1 = 3.5 L
  • Initial pressure, P1 = 0.8 atm
  • Final pressure, P2 = 0.5 atm

We are required to calculate the final volume;

  • According to Boyle's law, the volume of a fixed mass of a gas and the pressure are inversely proportional at a constant temperature.
  • That is; P α 1/V
  • Mathematically, P=k/V
  • At two different pressure and volume;

           P1V1 = P2V2

In this case;

Rearranging the formula;

V2 = P1V1 ÷ P2

     = (0.8 atm × 3.5 L) ÷ 0.5 atm

    = 5.6 L

Therefore, the resulting volume is 5.6 L
