Densities, molecular weight and chemical formulas of some common gases can be found in the table below: 1) NTP - Normal Temperature and Pressure - is defined as 20oC (293.15 K, 68oF) and 1 atm ( 101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 30 in Hg, 760 torr)
While there are tables of pure water density between water's freezing point (0 °C or 32 °F) and its boiling point (100 °C or 212 °F), there isn't a straightforward formula which yields the exact value for a given temperature. To get around this, our water density calculator uses an approximate equation based on the 5 th order polynomial:

Let’s use to work out a formula for the pressure at a depth h from the surface in a tank of a liquid such as water, where the density of the liquid can be taken to be constant. We need to integrate (Figure) from [latex] y=0, [/latex] where the pressure is atmospheric pressure [latex] ({p}_{0}), [/latex] to [latex] y=\text{−}h, [/latex] the ...
Pressure in a fluid with a constant density. Let’s use Equation 14.9 to work out a formula for the pressure at a depth h from the surface in a tank of a liquid such as water, where the density of the liquid can be taken to be constant.
where p 1 is the external applied pressure, ρ is the density of the fluid, Δh is the difference in height of the static liquid, and g is the acceleration due to gravity. Pascal’s Law explicitly determines the pressure difference between two different heights (or depths) within a static liquid.
