A sample of methane gas collected at a pressure of 0.884 atm and a temperature of 6.00 C is found to occupy a volume of 26.5 L.
Genrish500 [490]

Answer:

1.03mole

Explanation:

Given parameters:

Pressure = 0.884 atm

Temperature  = 6°C  = 273 + 6  = 279k

Volume  = 26.5L

Unknown:

Number of moles  = ?

Solution:

To solve this problem, we 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  = 0.082atmdm³mol⁻¹K⁻¹  

T is the temperature

        n  = \frac{PV}{RT}    = \frac{0.884 x 26.5}{0.082 x 279}    = 1.03mole
