Calculating the Volume of Sulfur Dioxide Gas
What volume would 20.0 moles of sulfur dioxide occupy at 75.3 °C with a pressure of 3.50 atm?
Answer:
163 L
Explanation:
To find the volume, you need to use the Ideal Gas Law. The equation looks like this:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = moles
-----> R = constant (0.0821 L*atm/mol*K)
-----> T = temperature (K)
Before you can plug the given values into the equation, you first need to convert Celsius to Kelvin.
P = 3.50 atm R = 0.0821 L*atm/mol*K
V = ? L T = 75.3 °C + 273.15 = 348.45 K
n = 20.0 moles
PV = nRT
(3.50 atm)V = (20.0 moles)(0.0821 L*atm/mol*K)(348.45 K)
(3.50 atm)V = 572.1549
V = 163 L
What is the Ideal Gas Law equation? The Ideal Gas Law equation is PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.
