Answer:
V = 96.61 L
Explanation:
Given data:
Number of moles = 4.0 mol
Pressure = 780 torr (780/760 = 1.03 atm)
Temperature = 30°C
Volume of gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
30+273 = 303 K
1.03 atm × V = 4.0 mol × 0.0821 atm.L/ mol.K × 303 K
V = 99.505 atm.L / 1.03 atm
V = 96.61 L
