In a measurement of a man's density he is found to have a mass of 58.9 kg in air and an apparent mass of 1.0 kg when completely submereged in water with his lungs empty. If his lung capacity is 1.9 liters, what is his density when his lungs are full?
Correct answer: 985 kg/m^3
Okay, here is how I have been working it. Where am I going wrong?
1.9L(1000cm^3/1L)(1m^3/100cm^3)=1.9E1
58.9 kg-1.0 kg=57.9 kg/10^3 kg/m^3=5.79E-2 kg/m^3 +1.9E1 m^3=1.90E1 m^3
58.9 kg/1.90E1 m^3=3.105E-1 kg/m^3
Correct answer: 985 kg/m^3
