2 moles equals 8 g of helium or 12.046 x 1023 atoms
987 grams of Ra(OH)2 is equal to 3,78 moles.
124,60 grams of Fe3(PO4)2 are equal to 0,35 moles.
mol = mass/Mr rearrange mol x Mr = mass 2 x 126.9g = 253.8g
1 mole of helium equal 4,002602(2) grams.

Two moles of atoms is equal to Avogadro's number of atoms, which is approximately 6.022 x 10^23 atoms. This is a fundamental concept in chemistry, where moles are used to quantify the amount of a substance.
In a titration, the moles of the titrant added are equal to the moles of the analyte in the solution. At the endpoint, the moles of the titrant consumed are equal to the moles of the analyte present in the solution.
Since both the acid and the base have equivalent weights equal to their formula weights, 2 moles of KOH are needed to neutralize 2 moles of nitric acid.
To find the number of moles in 2 grams of HCl, you need to divide the mass by the molar mass of HCl. The molar mass of HCl is approximately 36.46 g/mol. Therefore, 2 grams of HCl is equal to 2/36.46 = 0.055 moles.
To find the number of moles in 92g of ethanol, we first need to know the molar mass of ethanol, which is approximately 46g/mol. Then, we divide the given mass by the molar mass to get the number of moles. So, 92g of ethanol is equal to 2 moles.
2,5 moles of silver is equal to 269,6705 g.
1 mole of helium equal 4,002602(2) grams.
One mole is 6.02 × 1023 molecules. So 2 molecules out of that 6.02 × 1023 would be 2/(6.02 × 1023) or 3.32 ×10-24 moles.
