26.98 grams
the mass of one mole od aluminum is 65.2 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.
6.02x1023 atoms = 1 Mole 5.6x1025 atoms = 5.6x1025 / 6.02x1023 = 93.02 moles Molecular weight of Aluminum = 27.0 g Therefore 93.02 Moles of Aluminum = 27.0 x 93.02 =2511.54 g 5.6x1025 atoms of Aluminum weighs 2511.54 grams.
The molar mass of aluminum is 26.98 g/mol. To find the number of atoms in 16.2 g of aluminum, first calculate moles (16.2 g / 26.98 g/mol), then use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms.
39.95 because that is the molar mass of Argon
1 gram mole of Aluminium is about 27g.
the mass of one mole od aluminum is 65.2 grams
Thast is one mole. 26.98 grams/per mole is the mass.
This question is a little confused. The gram-atomic mass for aluminum is approximately 27 (look at a periodic table if you want more significant figures; I don't recall them off the top of my head). It doesn't matter if you have a mole or a planet-sized mass of the stuff, the gram-atomic mass is always going to be the same.

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
6.02x1023 atoms = 1 Mole 5.6x1025 atoms = 5.6x1025 / 6.02x1023 = 93.02 moles Molecular weight of Aluminum = 27.0 g Therefore 93.02 Moles of Aluminum = 27.0 x 93.02 =2511.54 g 5.6x1025 atoms of Aluminum weighs 2511.54 grams.
To the nearest gram, molar mass of aluminium carbonate is 234 g/mol.
39.95 because that is the molar mass of Argon
The molar mass of aluminum is 26.98 g/mol. To find the number of atoms in 16.2 g of aluminum, first calculate moles (16.2 g / 26.98 g/mol), then use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms.
The molar mass of aluminum sulfate (Al2(SO4)3) is approximately 342 grams per mole.
The molar mass of Argon is 39.95g. Therefore 1 mole of Argon is 39.95g
