Calculate the volume of 0.684mol of carbon dioxide at s.t.p. show working
solong [7]

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

Explanation:

According to ideal gas equation:

PV=nRT

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

V = Volume of gas = ?

n = number of moles = 0.684

R = gas constant = 0.0821Latm/Kmol

T =temperature =273K   (at STP)

V=\frac{nRT}{P}

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

V=15.3L

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

Daniel [21]

Answer: 85.62 L represents volume (V).

Explanation:

Volume is defined as the amount or quantity of a given substance or an object.

According to ideal gas equation:

PV=nRT

P = pressure of gas = 4.95 atm

V = Volume of gas = 85.62 L

n = number of moles

R = gas constant =0.0821Latm/Kmol

T =temperature =313K

Thus 85.62 L represents volume (V).
