The noble gas is Kyrpton

Ideal gas equation

  • The ideal gas equation gives the relationship between moles volume, temperature and pressure of a gas

The ideal gas equation is give below:

PV = nRT

  • where P is pressure,
  • V is volume,
  • T is temperature,
  • n is number of moles and
  • R is molar gas constant; R = 8.314 LkPa/K.mol

number of moles n = mass/molar mass

n = m/Mm

therefore, the ideal gas equation becomes;

PV = mRT/Mm

Mm = mRT/PV

substituting the data provided

Mm = 1.07 * 308 * 8.314/90.3 * 0.363

Mm, molar mass = 83.6

the noble gas that has a mass of 83.6 is Krypton.

Therefore, the noble gas is Kyrpton
