Question

how does liquid pressure depend on density of the liquid

Answer 1

P.V =nRT
Where p is pressure,v is volume , n is moles, R is ideal gas constant , T is temperature.
We know,
p=nrt/v
As n = m/M where m=mass, M=molar mass
p = mrt/Mv we know d = m/v
Thus,
p= drt/M
Therefore, PM=drT.
Pressure is directly proportional to density .
