Answer:
P₂ = 3.86 atm .
Explanation:
We assume that during this change , the temperature of the gas remains constant .
So the gas will obey Boyle's law .
P₁ V₁ = P₂V₂
5.08 x 7.56 = P₂ x 9.94
P₂ = 3.86 atm .
I am looking for this answer too. Did you ever find it? I could really use the help
Answer:
11.9 moles Cl₂
Explanation:
To find the number of moles, 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 = 33.3 atm R = 0.0821 L*atm/mol*K
V = 11.5 L T = 120. °C + 273.15 = 393.15 K
n = ? moles
PV = nRT
(33.3 atm)(11.5 L) = n(0.0821 L*atm/mol*K)(393.15 K)
382.95 = n(0.0821 L*atm/mol*K)(393.15 K)
382.95 = (32.2776)n
11.9 = n
