Place ½ teaspoon of baking soda in each large container. if the baking soda is lumpy, first place it on a small plate and use the back of a spoon to break up the lumps. why is it important to break up the lumps?

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
