no.of molecule of ammonia=mole×avagadro no. ,, 6.022×10^21=mole×6.022×10^23 then mole is 10^-2 and mole=mass/molecular mass ,,, 0.01=mass/17 then mass is 0.17gm

Answer: The formula which is used is p V = n R T  ,

       where  

  • p  is the pressure
  • V  is the volume
  • n  is the number of moles
  • R  is the gas constant
  • T  is the temperature

Explanation:  V  =  n R T /p

     n = 6.023 × 10²² molecules NH ³ × 1 mol NH ³ /  6.022 × 10 ²³ molecules NH ³

         = 0.100 02 mol NH ³
