2 KI + Br2 2 KBr + I2 What is the mass in grams of bromine gas required to react with 16.34 grams of potassium iodide?

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

what is the question here. i think you messed up.
