the mass of one mole od aluminum is 65.2 grams
A mole of anything contains 6.02 x 10^23 atoms.
26.98 grams
It isn't. The mass of one mole of aluminum is less than the mass of one mole of copper. The number of atoms in one mole of aluminum is the same as the number of atoms in one mole of copper, which is 6.022 x 1023, also known as Avogodro's number.
26.98 grams
16.2 grams aluminum (1 mole Al/26.98 grams)(6.022 X 1023/1 mole Al) = 3.62 X 1023 atoms of aluminum ------------------------------------------

Gold, as it has the higher molar mass.

Thast is one mole. 26.98 grams/per mole is the mass.
1 gram mole of Aluminium is about 27g.
26.98 grams
There are Avogadro's Number of atoms present, which is one gram mole of aluminum. This is roughly 27 g.
For this you need the atomic mass of Al. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.2.00 moles Al × (27.0 grams) = 54.0 grams Al
16.2 grams aluminum (1 mole Al/26.98 grams)(6.022 X 1023/1 mole Al) = 3.62 X 1023 atoms of aluminum ------------------------------------------
The mass of one mile of a compound is found by adding up the atomic masses of each of the component elements. A mole of Al2O3 has mass of 2 × 26.98 + 3 × 16.00 = 101.96g

16. 2 grams aluminum (1 mole Al/26.98 grams)(6.022 X 1023/1 mole Al) = 3.62 X 1023 atoms of aluminum -------------------------------------------
Aluminium Sulphate is Al2(SO4)3 and its mass is27x2 + 96x3 = 342g/mole
Gold, as it has the higher molar mass.
