Calculate how many atoms of gold (Au) are present in 0.196 mol of Au ?
The density of gold (Au) is 19.32 g/mL. How many atoms are in a gold bar whose volume is 150 mL?
Consider the precious metal, gold (Au). It has the FCC structure and an atomic radius of 0.144 nm. It has an atomic mass of 52.00 g/mole and an atomic number 79. Avogadro's nmber is 6.023 x 1023 atoms/mole. Calculate the planar density for (111) plane (in atoms/nm2). Hint: The area of an equilateral triangle is a r e a = 3 2 s 2 where s is the length of the side of the triangle.
