just the last question please

In April 2010, the worst oil spill ever recorded occurred when an explosion and fire on the Deepwater Horizon offshore oil-drilling rig left 11 workers dead and began releasing oil into the Gulf of Mexico. One of the attempts to contain the spill involved pumping drilling mud into the well to balance the pressure of escaping oil against a column of fluid (the mud) having a density significantly higher than those of seawater and oil. In the following problems, you may assume that seawater has a specific gravity of 1.03 and that a hypothetical subsea wellhead is 5835ft below the surface of the Gulf. Gauge Pressure Estimate the gauge pressure (psig) in the Gulf at a depth of 5835ft. psig Required Specific Gravity Measurements indicate that the pressure inside the wellhead is 3750 psig. Suppose a pipe between the surface of the Gulf and the wellhead is filled with drilling mud and balances that pressure. Estimate the specific gravity of the drilling mud. Hint Attempts: unlimited Mud Composition Check significant figures and units. Make sure that you are solving for mass fraction and not volume fraction. The drilling mud is a stable slurry of seawater and barite (SG = 4.37). What is the mass fraction of barite in the slurry? Hint Attempts: unlimited
