What is the density of the liquid being used in this experiment? 

Use the equation of the line to extrapolate the pressure on a sample when it is submerged at a depth of 5 meters. 

If atmospheric pressure is given as 1.013 x 105 N/m2, what is the accuracy of this experiment's value for atmospheric pressure?
