The pressure difference between the top and bottom surfaces is due to the weight of the fluid column, which is 2.60 kPa (112.00 kPa - 109.40 kPa). Using the formula for pressure difference, ΔP = ρgh, where h is 0.25 m, and g is 9.81 m/s², we solve for ρ: ρ = ΔP / (gh) = 2600 Pa / (9.81 m/s² * 0.25 m) = 1060 kg/m³.
