Answer:
1.28 x 10^5 Pa
Step-by-step explanation:
The absolute pressure at the bottom of the tank of water is given by:

where
is the atmospheric pressure
is the water density
g = 9.8 m/s^2 is the acceleration of gravity
h = 2.50 m is the heigth of the column of water
Substituting into the formula, we find
