Put the following three molecules in order of decreasing F-X-F bond angle, where X is the central atom. Support your ranking with Lewis structures of each molecule (use wedge/dash notation to show geometry). Label bond angles. (i) BF_3 (ii) XeF_4 (iii) RnF_2

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

you gotta add the following molecules so we can give u an answer
