The mass of nitrogen dioxide contained in a 4.32 l vessel at 48 °c and 141600 pa is g.

The mass of nitrogen dioxide contained in a 4.32 L vessel at 48 degrees and 141600 pa is 10.54 g.

Explanation:

 We know that

        ........... 1

Here given that

 P = 141600 pa  = 141.6

 T = 48 degrees = 48 + 273 k  

R  = 8.314

V = 4.32 L

Upon substituting these values in equation 1 , we get

    n = 0.229

  We know that molar mass of nitrogen dioxide is 46 .

       So mass of 0.229 become

                      ⇒  

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
