How many moles are in a 2.0 cm * 2.0 cm * 2.0 cm cube of
copper?
The atomic mass number of copper is . Assume that atoms in solid copper form a cubic crystal lattice. To envision this, imagine that you place atoms at the centers of tiny sugar cubes, then stack the little sugar cubes to form a big cube. If you dissolve the sugar, the atoms left behind are in a cubic crystal lattice. What is the smallest distance between two copper atoms?
of gas undergoes the process shown in Figure P16.38. What are
(a) temperature ,
(b) pressure , and
(c) volume ?
The nucleus of a uranium atom has a diameter of 1.5 * 10-14 m
and a mass of 4.0 * 10-25 kg. What is the density of the nucleus?
