What is the pressure in atmospheres of 0.100 moles of O₂ gas in a 2.0 Liter container at a temperature of 75 ° C?

Question

Quizplus · Accepted Answer

We can use the Ideal Gas Law equation:

PV = nRT

where P is the pressure in atmospheres, V is the volume in liters, n is the number of moles, R is the gas constant (0.08206 L atm/mol K), and T is the temperature in Kelvin.

First, we need to convert the temperature from Celsius to Kelvin:

75 °C + 273.15 = 348.15 K

Next, we can plug in the given values:

P(2.0 L) = (0.100 mol)(0.08206 L atm/mol K)(348.15 K)

Solving for P, we get:

P = (0.100 mol)(0.08206 L atm/mol K)(348.15 K)/(2.0 L)

P = 1.43 atm

Therefore, the answer is choice C, 1.43 atm.
