Question 3

A pressure sensor is positioned 1.8 m below the surface of an unidentified liquid in a laboratory column. The pressure caused by the liquid at the sensor is 15 120 Pa15\,120\ \text{Pa}15120 Pa. gravitational field strength, g=9.8 N/kgg = 9.8\ \text{N/kg}g=9.8 N/kg.

What is the density of the liquid?
