Problem 9:In a total-immersion measurement of a woman's density, she is found to have a mass of65kg in air and an apparent mass of0.0975kg when completely submerged with lungs almost totally empty.

Part (a)What mass, in kilograms, of water does she displace?

m_w =

Part (b)What is her volume, in cubic meters?

V =

Part (c)Calculate her average density, in kilograms per cubic meter.

_ave =

Part (d)If her lung capacity is 1.75 L, is she able to float without treading water with her lungs filled with air? Assume the density of air is 1.29 kg/m³.

No

Yes
