in the space between two stars, the temperature of a gas cloud is 12K and the density of hte gas is 1.2 x10^-17 atom/m³. the absolute pressure of the gas is ?????

Given,

Density of gas = 1.2 x10^-17 atom/m³

Therefore,

Volume = 1 m³

Number of moles of gas = 1.2 x 10^-17/ 6.022 x 10²³

  = 2 x 10^-41

Substituting the values in,

PV = nRT

  P = 2 x 10^-41 x 8.314 x 12 /1

   = 2 x 10^-39  Pa
