How much epson salt will be needed to float my 150-pound body in a tap water filled 50-gallon (rough estimate) bathtub?

You could approximate the amount of salt by making the salinity of the tub a little higher than the salinity of the human body. The human body is about 50-70% water, and the buoyancy of fat tends to offset the high density of the skeleton. Human blood and body fluids contain roughly 0.9 percent sodium chloride. So a salt concentration greater than 9000 parts per million, or more than 9 grams of Epsom salt per liter of water should do the trick.

There is a certain amount of salt that will disolve in the water at room temp...to get more salt to disolve in the water you will have to heat up the water to make a super saturated solution which should give you a better chance of your body floating in the water

That is a complex problem. It depends on factors such as the density of your body, the mineral content of the tap water where you live, the temperature of the water. Just buy a few bags of 'epsom' salts and experiment.
