A sample of carbon dioxide gas at 125°c and 248 torr occupies a volume of 275 l. What will the gas pressure be if the volume is increased to 321 l at 125°c?.

Respuesta :

Eduard22sly

The new pressure of gas when the volume of the gas is increase to 321 L at 125 °C is 212.46 torr

Data obtained from the question

  • Initial pressure (P₁) = 248 torr
  • Initial volume (V₁) = 275 L
  • Temperature = 125 °C = constant
  • New Volume (V₂) = 321 L
  • New pressure (P₂) =?

How to determine the new pressure

The new pressure of the gas can be obtained by using the Boyle's law equation since the temperature is constant. This is illustrated below:

P₁V₁  = P₂V₂

248 × 275 = P₂ × 321

68200 = P₂ × 321

Divide both side by 321

P₂ = 68200 / 321

P₂ = 212.46 torr
