Answer: The volume of 0.684 mol of carbon dioxide at s.t.p. is 15.3 L

Explanation:

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 1 atm (at STP)

V = Volume of gas = ?

n = number of moles = 0.684

R = gas constant = [tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]273K[/tex]   (at STP)

[tex]V=\frac{nRT}{P}[/tex]

[tex]V=\frac{0.684\times 0.0821L atm/K mol\times 273K}{1atm}[/tex]

[tex]V=15.3L[/tex]

Thus the volume of 0.684 mol of carbon dioxide at s.t.p. is 15.3 L
