Answer:

i think this is the answer you can try it tho...

Explanation:

Notice that the value 12.01 grams of natural carbon is the same as the atomic mass value (12.01 amu). It also tells us that 26.98 grams of aluminum contains exactly 6.022 x 1023 atoms of aluminum.

There are 3.524X 10 ^23 atoms of Aluminium in the can

Relationship between atoms  and Avogadro Number

An atom is the smallest indivisible unit of matter which forms a chemical element.

The Avogadro's number tells us number of atoms, ions, or molecules in one mole of any substance.

This number is equal to 6.02214076 × 10^23.

To find the atoms of aluminum in the can, we first convert to number of moles

Number of moles of Aluminium =Mass/Molar mass

Number of moles of Aluminium =15.8 grams/26.982 g/mol

Number of moles of Aluminium =0.5855moles

Now ,

According to  Avogadro constant is 1 mole = 6.02 x10^23

Therefore, 0.5855moles=0.5855moles x ( 6.02x 10^23)= 3.524X 10 ^23 atoms of Aluminium
