The pressure exerted by 6.0 ~g of methane gas in a 0.03 ~m ^3 vessel at 129^ C is (Atomic masses : C =12.01, H =1.01 and R =8.314 JK ⁻¹ ~mol ⁻¹ )

Options

  1. A215216 ~Pa
  2. B13409 ~Pa
  3. C41648 ~Pa
  4. D31684 ~Pa

Correct answer

C. 41648 ~Pa

Step-by-step solution

Given, volume, V =0.03 ~m ^3 temperature, T =129+273=402 ~K mass of methane, w=6.0 ~g mol. mass of methane, M=12.01+4 1.01=16.05 From, ideal gas equation, aligned & pV = nRT & p = 6 16.05 8.314 402 0.03 =41648 ~Pa aligned
