A gold refinery produces a gold nugget weighing 170 lb.  The density of gold is 19.32 g/cm3. Calculate the volume of the gold nugget in cubic centimeters (cm3). Volume =  cm3 (give the number written with 4 digits). If the gold is drawn into a wire whose radius is 16 mm, how many feet of gold can be obtained?  The volume of a cylinder is πr2h.  Hint:  you need to solve for h and use the volume calculated in part (a). Length of wire (or height of cylinder) =  ft (Answer should have 2 significant figures

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
