The density is still rho. It doesn't change. The density of a substance is the density of the substance. It doesn't depend on how much of it you have.
Gravity is often assumed to be the same everywhere on Earth, but it varies because the planet is not perfectly spherical or uniformly dense. In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation

Answer: 53 kPa
Explanation:
Absolute pressure is a pressure value referred to absolute zero or vacuum. This value indicates the total pressure to which a body or system (the chamber in this situation) is subjected, considering the total pressure acting on it.
In this sense, the equation that will be useful in this case is:
(1)
Where:
is the atmospheric pressure
is the vacuum pressure
is the absolute pressure
Isolating
from (1):
(2)
(3)
Finally:
This is the absolute pressure in the chamber
