the gravitational force exerted on a solid object is given by F=mg, where F is the force in Newtons, m is the mass in kg and g is the acceleration due to gravity (9.81m/s^2)
a) use the definition of the pascal to calculate the mass (in kg) of the atmosphere on 1m^2 of ocean
b) Osmium (Z=76) has the highest denisty of any element (22.6g/ml). If an ismium column is 1 m^2 in area, how high must it be for its pressure to equal atmospheric pressure? (use answer from part a in calculation)
