Answer: The volume of 0.684 mol of carbon dioxide at s.t.p. is 15.3 L
Explanation:
According to ideal gas equation:

P = pressure of gas = 1 atm (at STP)
V = Volume of gas = ?
n = number of moles = 0.684
R = gas constant = 
T =temperature =
(at STP)



Thus the volume of 0.684 mol of carbon dioxide at s.t.p. is 15.3 L
Answer:
I think it's pf5or I don't know how to make the answer
Explanation:
,
Answer:
The volume will decrease.
Explanation:
According to Charles' Law, the volume of a gas is directly proportional to its temperature.
V = kT
Thus, if T decreases, V decreases.
