Calculate the number of stearic acid molecules in the Trial 1 monolayer. (The surface area of a stearic acid molecule is 0.21 nm2/molecule.)

indium, and thallium have three electrons i think

if you mean hydrogen and oxygen then water is the product

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
