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

                      ⇒  

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
