Question

One litre of a gas collected at NTP will occupy at 2 atmospheric. pressure and 27 to the power of 0 C:

  1. fraction numerator 300 over denominator 2 cross times 273 end fraction litre    
  2. fraction numerator 2 cross times 300 over denominator 273 end fraction litre    
  3. fraction numerator 273 over denominator 2 cross times 300 end fraction litre    
  4. fraction numerator 2 cross times 273 over denominator 300 end fraction litre    

The correct answer is: fraction numerator 300 over denominator 2 cross times 273 end fraction litre
