How many moles of chlorine gas will be required to react with sufficient iron to produce 14 moles of iron (III) chloride? 2Fe(s) + 3Cl2(g) ® 2FeCl3(g)

its mg hope this

imma come back to you hold on

a) the particles of the chair are strongly held together.

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
