Answer:
approximately 3.70 atm.
Explanation:
To find the pressure in atmospheres, we can use the ideal gas law formula: PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is ideal gas constant, and T is the temperature in Kelvin.
First, we need to convert the temperature from Celsius to Kelvin: T(K) = T(C) + 273.15
T(K) = 140.68 + 273.15 = 413.83 K
Next, we can plug in the given values into the ideal gas law formula:
P = (nRT) / V
P = (6.675 mol * 0.0821 atm*L/mol*K * 413.83 K) / 59.4 L
Calculating the pressure:
P = (220.03) / 59.4
P ≈ 3.70 atm
Therefore, the pressure is approximately 3.70 atm.
