which option is an example of a physical property?

a) conductivity

b) reactivity

c) rusting ability

d) ph

they both have a y in them

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

50.23 i believe is correct but don't quote me on that.
