Use Avogadro's constant which expresses the number of elementary entities per mole of substance and it has the value 6.022...)×1023 mol-1
To calculate the number of moles in 1,000,000,000 molecules of H2O2, divide the number of molecules by Avogadro's number (6.022 x 10^23 molecules/mol). So, 1,000,000,000 molecules / 6.022 x 10^23 molecules/mol ≈ 1.66 x 10^-14 moles of H2O2.
To find the number of molecules produced, first calculate the number of moles of H2 using its molar mass. Then, use the balanced chemical equation to relate the number of moles of H2 to NH3. Finally, convert the moles of NH3 to molecules using Avogadro's number, which is 6.022 x 10^23 molecules/mol.
To find the number of molecules, first calculate the amount of O2 in moles using the ideal gas law. Then use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
To calculate the number of molecules in 15 grams of ethane (C2H6), first find the molar mass of C2H6, which is 30.07 g/mol. Next, calculate the number of moles in 15 grams using the formula: moles = mass / molar mass. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
If you meant 1.5*10^23 and not 1.51023 molecules, see below:1.5*10^23 molecules / (6.022*10^23 molecules/mol)= 1.5/6.022 mol=.25 moles, rounded to two significant figures.
2 moles.
CH is not a molecule.
CH is not a molecule.
The answer is 6,022140857.1023 x 8 = 48,177126856.1023 molecules.
The mass of 3 mol of ammonia is 51,093 g; the number of ammonia molecules in 3 moles is18,066422571.10e23.

To find the number of moles in 8.23 x 10^24 molecules of calcium carbonate, you first need to determine the molar amount of molecules in one mole of calcium carbonate by using Avogadro's number. Then, divide the given number of molecules by the molar amount to calculate the number of moles.
To calculate the number of argon molecules, first find the number of moles of argon in 119.98 grams using the molar mass of argon (39.95 g/mol). Next, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. Simply multiply the number of moles by Avogadro's number to determine the total number of argon molecules.
