0100 moles of aluminum contain 602,214.10e23 atoms.

The gram atomic mass of phosphorus is 30.9738, and by definition, a mole of such atoms contains Avogadro's Number of atoms. Therefore, 100 g of phosphorus contains 100/30.9738 or 3.23 moles, to the justified number of significant digits.

100 times Avogadro's Number = 6.022 X 1025.

Gold has a molar mass of 196.96655 grams per mole. 100 grams then is equal to .508 moles which makes 3.059 E23 atoms of gold.

100/150.158 is 0.666 moles

100/27 = 3.71 moles

100 grams of H2O is equal to 5,555 moles.

4.46 moles

For this problem you need the atomic masses of the elements to find the molecular mass (added atomic masses). Then take the atomic mass of Cl and divide it by the molecular mass (multiplied by 100) to get a percent. This will be the percent of Cl in all compounds of HCl. Then you can use this percent and apply it to the 2 moles.H- 1.00Cl- 35.5HCl- 36.535.5 / 36.5 Ã— 100 = 97.3% Cl in HClSo we know that in 2 moles of HCl, 97.3% of it is Cl.97.3% of 2.00 moles HCl = 1.95 moles of Cl in 2 moles HClNow we have to find out how many atoms this is (convert moles to atoms). Take the number of moles and multiply it by Avogadro's constant, 6.02 Ã— 1023.1.95 moles Cl Ã— 6.02 Ã— 1023 = 1.17 Ã— 1024atoms of Cl in 2 moles of HCl

100 molecules of CO2 equals 0,166.10e-21 moles.

moles = mass/Mr moles = 100/(23+16+1) moles of NaOH = 2.5mol

100 g KMnO4 is equivalent to 0,633 moles.

if you have 100 liters how many moles does that equal?

100 g NaCl equal 1,711 moles.

100 grams water (1 mole H2O/18.016 grams) = 5.55 moles of water ================

100 grams of carbon dioxide contain 2,27 moles.

Molar mass of KMnO4 (from the periodic table) = 158, and 100/158 = 0.633mol.

Bromine at -100 oC is a solid.

the answer to this question is 4.9$ for 100 grams of pure bromine.
