Explanation:
We are given: volume = 2.55L
At STP: Temperature = 273.15 K
: Pressure = 1 atm
: R = 0.08205 L.atm/mol.K
Using the ideal gas law:
[tex]\begin{gathered} PV\text{ = nRT} \\ \\ \therefore\text{ n = }\frac{PV}{RT}\text{ = }\frac{1\times2.55}{0.08205\times273.15}\text{ = 0.11 mol} \end{gathered}[/tex]Answer:
n = 0.11 mol
