How many atoms present in 3 moles of chromium?
Chromium and other metals with metallic bonding do not literally have "moles" but rather "formula units" with similar properties. The formula unit is a single atom; therefore, the number of atoms in 3 formula units is 3 times Avogadro's Number or about 1.81 X 1024 atoms.
How many atoms of aluminum sulfur and oxygen are in 3 molecules of aluminum sulfate?
1 formula unit of aluminum sulfate has the formula Al2(SO4)3. So there are 2 atoms of aluminum, 3 atoms of sulfur and 12 atoms of oxygen in 1 formula unit of aluminum sulfate. There are no molecules of aluminum sulfate. They are called formula units.
What is the mass of 9.871023 formula units of aluminum oxide?
Assuming that the number "9.871023" would or should have been written as "9.87 X 1023" if the typographical resources to do so were available to the questioner: Avogadro's Number, which is the number of formula units in a mole of any material, is about 6.022 X 1023. The gram formula mass for aluminum oxide is 101.96. Therefore, the mass of the stated number of formula units of aluminum oxide is: 101.96(9.87/6.022) or about 164 grams, to the justified number of significant digits.
How many moles are in formula units?
One mole of formula units = 6.022 x 1023 formula units.
What is the chemical formula for one unit of Al2SO4 plus three units of BaCl2 two units of AlCl2 plus three units of BaSO4?
The chemical equation is Al2(SO4)3 + 3BaCl2 --> 2AlCl3 + 3BaSO4. (I corrected the formulas containing aluminum.)
How many sulfur atoms are in 1.10 mol of aluminum sulfide?
Aluminum sulfide is Al2S3, which has 3 sulfur atoms per formula unit. 1.10mol means 1.10(6.02x1023), which is 6.62x1023 formula units. Multiple that by 3 to get your sulfur atoms: 6.62x1023(3) = 1.99x1024 sulfur atoms.

What is the number of formula units that are in 5.68 moles of magnesium oxide?
5.68 mol MgO x 6.02E23 formula units / 1 mol = 3.42E24 Formula Units
What is the atomic mass for aluminum?
The atomic mass for Aluminum is 26.98 atomic mass units or amu.
