An empty water bottle is full of air at 15°C and standard pressure. The volume of the bottle is 0.500 liter. How many moles of air are in the bottle?

Respuesta :

Answer:  0.02 moles

Explanation: Using ideal gas equation:  

[tex]PV=nRT[/tex]

[tex]n=\frac{PV}{RT}[/tex]

P = pressure = standard pressure= 1 atm

V = volume = 0.500L

n = no of moles = ?

R = gas constant =0.0821 Latm\molK

T= temperature = [tex]15^0C[/tex] = (15+273)K= 288K

[tex]n=\frac{1\times 0.500}{0.0821\times 288}=0.02moles[/tex]

Answer: the water bottle contains 0.0211 mole of air
