Question

A 0.245-L flask contains 0.467 mol of CO₂ at 159 °C. Calculate the pressure:

a) 4.56 atm
b) 5.34 atm
c) 2.14 atm
d) 6.78 atm

Answer 1

The total pressure in the flask is 2.46 atm.

Step-by-step explanation:

To calculate the total pressure in the flask, we need to use the ideal gas law. The ideal gas law equation is:

PV = nRT
Where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin. We can rearrange the equation to solve for P:

P = (nRT) / V

Now we can plug in the values:
P = (0.0388 mol + 0.147 mol + 0.0803 mol) * (0.0821 L * atm / K * mol) * (298 K) / (5.73 L)
P = 2.46 atm
