A 180 lb man weighs 5 lb in water. What is his percent body fat? Assume that fat has a density of 0.90 g/cc and muscle has a density of 1.06 g/cc. Water has a density of 1.0 g/cc.
Although we are given the weight in lbs, it is okay to work with it like mass (as grams) or even as buoyant force...why?
Is this bc both sides of the equation (mass of fat and mass of muscle) will be in the same unit, so it doesn't matter?
What is the total mass? m-total = m-muscle + m-fat
This was the first question of a series of questions and I don't understand how we can calculate the mass without a volume...I don't understand the relationship between the weight and volume displaced.
