Question
In an immersion measurement of a woman's density, she is found to have a mass of 62.0 kg in air and an apparent mass of 0.0850 kg when completely submerged with lungs empty. (a) What mass of water does she displace? (b) What is her volume? (c) Calculate her density. (d) If her lung capacity is 1.75 L, is she able to float without treading water with her lungs filled with air?
1. $61.9 \textrm{ kg}$
2. $0.0619 \textrm{ m}^3$
3. $1.00 \times 10^3 \textrm{ kg/m}^3$
4. Yes, they will float without treading water.
