You come across an open container which is filled with two liquids. since the two liquids have different density there is a distinct separation between them. water fills the lower portion of the container to a depth of 0.209 m which has a density of 1.00 × 103 kg/m3. the fluid which is floating on top of the water is 0.300 m deep. if the absolute pressure on the bottom of the container is 1.049 × 105 pa, what is the density of the unknown fluid? the acceleration due to gravity is g = 9.81 m/s2 and atmospheric pressure is p0 = 1.013 × 105 pa.

Explanation:
P ( pressure at the bottom of the container) = 1.049 × 10^5 pa
Using the formula of pressure in an open liquid
Pw ( pressure due to water) = ρhg where ρ is density of water in kg/m³, h is the height in meters, and g is acceleration due to gravity in m/s²
Pw = 1000 × 9.81 ×0.209 = 2050.29 Pa
P( atmospheric pressure) = 1.013 × 10^5 Pa
Pl ( pressure due to the liquid) = ρ(density of the liquid) × h (depth of the liquid) × g
Subtract each of the pressure from the absolute pressure at the bottom
P(bottom) - atmospheric pressure
(1.049 × 10^5) - (1.013 × 10^5) = 0.036 × 10^5 = 3600 Pa
subtract pressure due to water from the remainder
3600 - 2050.29 = 1549.71 Pa
1549.71 = ρ(density of the liquid) × h (depth of the liquid) × g
ρ (density of the liquid) = 1549.71 / (h × g) = 1549.71 / (0.3 × 9.81) =526.57 Pa

The orbital diagram represents the filling of electrons in the sub levels of an orbit. The filling of the orbitals in sub- levels follow some basic rules and principles.
The orbital diagram of an orbit containing 16 electrons will be as follows:
1s²2s²2p⁶3s²3p⁴
The maximum number of electrons in each sublevel of the orbitals are: 2 electrons for s-sublevel with one orbital 6 electrons for p-sublevel with three orbital 10 electrons for d-sublevel with five orbital 14 electrons for f-sublevel with seven orbital
