Final answer:
The pressure in the 5.00 L tank with 4.40 moles of oxygen at 39.3 °C is 84.44 atm.
Step-by-step explanation:
To find the pressure in the tank, we can use the Ideal Gas Law equation:
PV = nRT
Where:
- P is the pressure
- V is the volume
- n is the number of moles
- R is the gas constant
- T is the temperature in Kelvin
First, let's convert the temperature from Celsius to Kelvin:
T = 39.3 °C + 273.15 = 312.45 K
Then, we can plug in the values:
P(5.00 L) = (4.40 mol)(0.0821 L·atm/K·mol)(312.45 K)
Simplifying the equation, we find:
P = (4.40 mol)(0.0821 L·atm/K·mol)(312.45 K) / 5.00 L
P = 84.44 atm
Therefore, the pressure in the tank is 84.44 atm.
