The volume occupied by a given mass of gas at 298298 K is 3535 mL at 11 atmospheric pressure. Calculate the volume of the gas if pressure is decreased to 0.750.75 atmosphere at constant temperature.

Options

  1. A46.6646.66 mL
  2. B42.742.7 mL
  3. C50.250.2 mL
  4. D49.249.2 mL

Correct answer

A. 46.6646.66 mL

Step-by-step solution

According to Boyle's law, at constant temperature, P1V1=P2V2P_1 V_1 = P_2 V_2.

Given:
P1=1P_1 = 1 atm
V1=35V_1 = 35 mL
P2=0.75P_2 = 0.75 atm

Substituting the values:
1×35=0.75×V21 \times 35 = 0.75 \times V_2

V2=350.75=1403=46.66V_2 = \dfrac{35}{0.75} = \dfrac{140}{3} = 46.66 mL

Answer: 46.6646.66 mL
