What is the pressure inside a 2.0 L bottle filled with 0.25 mol of carbon dioxide gas at 25 °C?

3.1atm

Explanation:

Given parameters:

Volume of gas = 2L

Number of moles  = 0.25mol

Temperature  = 25°C = 25 + 273  = 298K

Unknown:

Pressure of the gas = ?

Solution:

To solve this problem, we use the ideal gas equation.

This is given as;

       PV  = nRT

P is the pressure

V is the volume

n is the number of moles

R is the gas  constant  = 0.082atmdm³mol⁻¹K⁻¹

T is the temperature

          P  =  

 Now insert the parameters and solve;

         P  =   = 3.1atm
