Answer :
Considering the definition of molar mass, there are 162 grams of Al in 6 moles of Al.
Definition of molar mass
The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.
Mass of 6 moles of Al
You want to determine the mass in 6 moles of Al. So, being the molar mass of Al is 27 g/mole, you can apply the following rule of three: If by definition of molar mass 1 mole of Al contains 27 grams, 6 moles of Al contains how much mass?
mass= (6 moles× 27 grams) ÷1 mole
mass= 162 grams
In summary, there are 162 grams of Al in 6 moles of Al.
