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

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃ → 3 nicl₂ + 2 albarium and copper bromideba + cubr → no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn → znso₄ + na
