Answer:

0.1mole

Explanation:

Given parameters:

Pressure = 0.0884atm

Temperature  = 6°C  = 6 + 273  = 279K

Volume occupied  = 26.5L

Unknown:

Number of moles  = ?

Solution:

To solve this problem, we are going to use the ideal gas equation:

           PV  = nRT

P is the pressure

V is the volume

n is the number of moles

R is the gas constant  = 0.082atmLmol⁻¹k⁻¹

T is the temperature.

  Insert the parameters and solve for n;

     0.084 x 26.5  = n x 0.082 x 279

              n  = 0.1mole
