An "empty" container is not really empty if it contains air. how many moles of nitrogen are in an "empty" two-liter cola bottle at atmospheric pressure and room temperature (25∘c)? assume ideal behavior.

number of moles = 0.08175 moles

Explanation:

To solve this question, we will use the ideal gas law:

PV = nRT

where:

P is the pressure = 1 atm

V is the volume of the gas = 2 liters

n is the number of moles we want to find

R is the general gas constant = 0.0821 L-atm/mol-K

T is the temperature = 25°C = 25 + 273 = 298°K

Now, substitute with the givens in the equation to get n as follows:

PV = nRT

1 * 2 = n * 0.0821* 298

n = moles

Hope this helps :)
