Answer: The volume occupied by 2.50 moles of 
gas at STP is 56.0L
Explanation:
According to ideal gas equation:
P = pressure of gas = 1 atm (at STP)
V = Volume of gas = ?
n = number of moles = 2.50
R = gas constant =
T =temperature =
(at STP)
Thus the volume occupied by 2.50 moles of gas at STP is 56.0L
