Answer:
<h2>252.9 kPa</h2>
Explanation:
The new pressure can be found by using the formula
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question we have
We have the final answer as
<h3>252.9 kPa</h3>

An empirical formula presents the atoms of all the elements with the most simplified whole number ratios. In other words, divide each subscript by their greatest common factor.
The greatest common factor of 2 and 4 is 2.
2/2 = 1
4/2 = 2
So, the empirical formula for tetrachloroethene is CCl₂.
