The volume occupied by a given mass of gas at 298 K is 35 mL at 1 atmospheric pressure. Calculate the volume of the gas if pressure is decreased to 0.75 atmosphere at constant temperature.

Options

  1. A46.66 mL
  2. B42.7 mL
  3. C50.2 mL
  4. D49.2 mL

Correct answer

A. 46.66 mL

Step-by-step solution

According to Boyle's law, at constant temperature, P₁ V₁ = P₂ V₂ . Given: P₁ = 1 atm V₁ = 35 mL P₂ = 0.75 atm Substituting the values: 1 35 = 0.75 V₂ V₂ = 35 0.75 = 140 3 = 46.66 mL Answer: 46.66 mL
