What is the volume of a gas at RTP and STP?

Answer 1

Since you did not specify ideality, I will have to assume an ideal gas. Nevertheless, if you want my response to be more accurate, you will have to provide your equation of state.

We also make use of the most recent IUPAC RTP and STP:

Therefore, its MOLAR volume is provided by

#color(blue)(barV_(RTP)^"id") = (RT_(RTP))/P#

#= (("0.083145 L"cdot"bar/mol"cdot"K")("298.15 K"))/("1 bar")#

#=# #color(blue)("24.790 L/mol")#

#color(blue)(barV_(STP)^"id") = (RT_(STP))/P#

#= (("0.083145 L"cdot"bar/mol"cdot"K")("273.15 K"))/("1 bar")#

#= (273.15)/(298.15)barV_(RTP)^"id"#

#=# #color(blue)("22.711 L/mol")#

At RTP (Room Temperature and Pressure), the volume of a gas is 24.45 L/mol. At STP (Standard Temperature and Pressure), the volume of a gas is 22.414 L/mol.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
