Answer:
Explanation:
In order to find the volume , we use the formula for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the final volume
From the question
P1 = 12 atm
V1 = 9 L
P2 = 6 atm
We have
We have the final answer as
Hope this helps you
i cant see the whats in the picture
89.88 g
Atomic Mass of Ar: 39.948
Mass = moles * AM
Replacing moles = 2.25 and AM = 39.948 you get the mass of Ar:
Mass = 2.25 * 39.948
Mass = 89.88 g
