Use the periodic table to determine which of the following could be an isotope of bromine (Br).
Check all that apply.
Z = 79, A = 196
Z= 35, A = 79
A = 79, N = 44
D
Z = 44, N = 44

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
