While calculating the empirical formula for a compound containing elements X and Y, Haya found the moles to be X (1) Y (2.67) . How would the empirical formula be properly written?

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
