How much liquid is needed to prepare 625.8mL of a solution that has a new concentration of 11.2M if the stock solution is 28.9M?
Type your answer.

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
