What volume of 1.25 M HCl would need to be diluted to prepare 375 mL of a 0.500 M HCl Solution?

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

since electrons are negative the answer is neagtaive
