A vessel containing nitrogen gas is supplied a heat of 498 ~J , so as to raise the temperature of the gas by 40^ C at constant pressure. The mass of nitrogen gas in the vessel is (Molecular mass of nitrogen =28 ~g ; Universal gas constant =8.3 ~J ~mol ⁻¹ ~K ⁻¹ )

Options

  1. A18 ~g
  2. B12 ~g
  3. C20 ~g
  4. D15 ~g

Correct answer

B. 12 ~g

Step-by-step solution

aligned & Q = nC _ P T & Q = M M ₀ ( f 2 +1 ) R T & 498= M 28 ( 5 2 +1 )(8.3) 40 & 498= M 28 7 2 8.3 40 & M =12 ~g & aligned
