Respuesta :
The pressure of the interstellar gas is 2.76*10-16 pascal.
What are interstellar gasses?
Most of the gas between stars in our galaxy and other galaxies is hydrogen and helium, which is dispersed at different densities between the stars. The gas ratios are comparable to those of the Sun. Star formation starts with interstellar gas as its raw material.
PV = nRT
V = 10-6 m3
n = 1/NA ; NA = avagadro number = 6.022*1023
n = 1.66*10-24
R = 8.314 J/K/mole
T = 20K
P = 1.66*10-24*8.314*20 / 10-6
P = 2.76*10-16 pascal
Therefore, the pressure of the interstellar gas is 2.76*10-16 pascal.
