2. If 0.544 moles of copper react with oxygen to form copper (I) oxide, how many grams of oxygen will be
consumed? You must start with a balanced chemical equation

oh it is true if thats what you are asking

it is the most commonly accepted one

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
