(Kravitz‚ Len‚ Ph.D. & H. Heyward‚ Vivian‚ Ph.D.). The calipers method involves measuring the skinfold thickness of the layer of fat just under the skin in several parts of the body with calipers.

ABSTRACT By calculating the difference in the mass of the hydrate copper (II) sulfate and the anhydride we were able to determine the mass of water in the hydrate. This information was then used to determine the empirical formula of the hydrate‚ defined as a compound formed by the addition of water to another molecule. In the first trial‚ the mass of water in the hydrate was determined to be 0.41 g‚ while in the second trial the mass of water was 0.52 g. Moles of water associated with a single

Composition of the Atmosphere The Earth is surrounded by air—a mixture of various gases that reaches up to a height of many kilometers. This envelope of air makes up our atmosphere. It is held in place by the Earth’s gravity. Almost all the atmosphere (97 percent) lies within 30 km (19 mi) of the Earth’s surface. The upper limit of the atmosphere is at a height of approximately 10‚000 km (about 6000 mi) above the Earth’s surface—a distance that is nearly as large as Earth’s diameter. The proportion
