Answer:
1.12 moles
Explanation:
To find the amount of moles, you need to use the Ideal Gas Law:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = moles
-----> R = Ideal Gas constant (0.08206 atm*L/mol*K)
-----> T = temperature (K)
After converting the temperature from Celsius to Kelvin, you can plug the given values into the equation and solve for "n".
P = 1.00 atm R = 0.08206 atm*L/mol*K
V = 25.0 L T = 0. °C + 273 = 273 K
n = ? moles
PV = nRT
(1.00 atm)(25.0 L) = n(0.08206 atm*L/mol*K)(273 K)
25.0 = n(22.4)
1.12 = n
