A cylinder contains hydrogen gas at pressure of 249   kPa and temperature 27 o C . Its density is: R = 8 .3   JK   Mol − 1   K − 1

Options

  1. A0 .2   kg   m - 3
  2. B0 .1   kg   m - 3
  3. C0 .02   kg   m - 3
  4. D0 .5   kg   m - 3

Correct answer

A. 0 .2   kg   m - 3

Step-by-step solution

For an ideal gas sample ( aligned & P = RT MW & = PMW RT = 249 10^3 2 10⁻³ 8.314 300 =0.199 & =0.2 ~kg / m ^3 aligned )
