Achemistry instructor provides each student with 8 test tubes at the beginning of the year. if there are 28 students per class, how many test tubes are required for three chemistry classes?

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
