Question

1. A gas occupies 22.4 L at STP. Calculate the temperature at which it will occupy a volume of 10 L at 2.46 atm?​

Answer 1

Hey Mate,

The Molar Volume of an ideal gas at STP, which we define to be  0∘C and 1 atm  arbitrarily (because we're old-fashioned and stuck in 1982) is 22.411 L/mol.

To calculate this we can use the Ideal gas law of  

P V  =  n  R  T

At STP (Standard Temperature and Pressure), we CHOSE:

P  =  1 atm  

V  =  ?

n  =  1 mol

R  =  0.082057 L⋅atm/mol⋅ K

T = 273.15 K

V  =  n  R  T  P  =  (1 mol) (  0.082057 atm. L mol⋅ K  )  273.15  K  1  atm =22.411 L

This is the volume of one mole of ideal gas at STP
