Multiply the number of molecules by the number of molecules per mole for that particular element or molecule (sum of the molecules/mole of each element in the molecule). The number of molecules per mole for any element can be found on charts and on the Periodic Table.
2 moles.
The answer is 6,022140857.1023 x 8 = 48,177126856.1023 molecules.

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.
The mass of 3 mol of ammonia is 51,093 g; the number of ammonia molecules in 3 moles is18,066422571.10e23.
You can calculate the number of molecules in a mole using Avogadro's number, which is 6.022 x 10^23. Simply multiply the number of moles by Avogadro's number to get the number of molecules. This calculation allows you to convert between moles and molecules.
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 moles of F2 molecules in 38g, we first need to determine the molar mass of F2, which is 38 grams/mol. Next, we can use the formula: moles = mass / molar mass. Therefore, the number of moles in 38g of F2 is 1 mole.
NH3 Molecules = ( 8.1 x 10^20 H atoms ) ( 1 NH3 molecule / 3 H atoms ) NH3 Molecules = 2.7 x 10^20 NH3 molecules NH3 moles = ( NH3 molecules ) / ( N Avogadro ) NH3 moles = ( 2.7 x 10^20 NH3 molecules ) / ( 6.022 x 10^23 molecules / mole ) NH3 moles = 4.48 x 10^-4 NH3 moles <--------------
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.
