How many moles of aluminum are in this aluminum can? (25 pts) Calculate the number of aluminum atoms in this can. (25 pts) The Amount of Aluminum is 12.69g

a)No of moles of Aluminium=0.4703

b)number of aluminum atoms=2.832 x 10^23 atoms

Explanation:

a)Given that The Amount/ Mass of Aluminum is 12.69g

We know that

No of moles =Mass/ Molar mass

Molar mass of Aluminium, Al is 26.982 g/mol

No of moles =12.69g/26.982 g/mol

No of moles =0.4703

Also

b) 1  mole of aluminium must contain  6.022  x 10^23  atoms of aluminium  

which is  known as Avogadro's constant.

Therefore, 0.4703 moles will contain 0.4703 x  6.022  x 10^23  atoms =2.832 x 10^23 atoms

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /
