4,5.10e28 molecules of sodium fluoride NaF are equal to 0,745.10e5 moles.
1,125 moles of sodium sulfate contain 6,774908464125.10e23 molecules.
To convert molecules to moles, you can use Avogadro's number, which is approximately (6.022 \times 10^{23}) molecules per mole. Therefore, to find the number of moles in 8.50 molecules of sodium sulfate, you calculate ( \frac{8.50 \text{ molecules}}{6.022 \times 10^{23} \text{ molecules/mole}} ), which gives approximately (1.41 \times 10^{-23}) moles of sodium sulfate.
1,46 moles of aluminum fluoride contain 35,16848.10e23 atoms.
The answer is 0,111 moles.
One mole of sodium chloride is composed of one mole of sodium atoms. Therefore, 3.6 moles of sodium chloride would require 3.6 moles of sodium.
There are 4.5 moles of sodium fluoride in 4.5 moles of sodium fluoride.
4.5 moles
To find the number of moles in 4.06 x 10^25 molecules of sodium fluoride, you would divide the number of molecules by Avogadro's number, which is approximately 6.022 x 10^23 molecules/mol. Therefore, 4.06 x 10^25 molecules / 6.022 x 10^23 molecules/mol ≈ 67.5 moles of sodium fluoride.
Multiply the number of moles by the molecular weight.
To find the number of grams in 4.5 moles of sodium fluoride, you would multiply the number of moles by the molar mass of sodium fluoride. The molar mass of sodium fluoride (NaF) is approximately 41 g/mol. So, 4.5 moles x 41 g/mol = 184.5 grams of sodium fluoride.
To find the grams of sodium fluoride needed, use the formula: grams = moles x molar mass. First calculate the moles by multiplying the volume (6.3 L) by the molarity (3.6 mol/L). Then multiply the moles by the molar mass of sodium fluoride (41.99 g/mol) to find the grams required. In this case, approximately 920 grams of sodium fluoride are needed.
1,125 moles of sodium sulfate contain 6,774908464125.10e23 molecules.
There are (5.24 \times 10^{22}) molecules of sodium acetate in 0.87 moles of sodium acetate. This is calculated by multiplying Avogadro's number (6.022 x 10^23 molecules/mol) by the number of moles given (0.87 mol).
To convert molecules to moles, you can use Avogadro's number, which is approximately (6.022 \times 10^{23}) molecules per mole. Therefore, to find the number of moles in 8.50 molecules of sodium sulfate, you calculate ( \frac{8.50 \text{ molecules}}{6.022 \times 10^{23} \text{ molecules/mole}} ), which gives approximately (1.41 \times 10^{-23}) moles of sodium sulfate.
There would be 4.38 moles of fluoride ions in 1.46 moles of aluminum fluoride, as the formula for aluminum fluoride is AlF3 with three fluoride ions per molecule of aluminum fluoride.
One: The formula for magnesium fluoride is MgF2. Since each mole of fluorine molecules, which have the formula F2, contains two moles of fluorine atoms, one mole of each is the right ratio.
1,46 moles of aluminum fluoride contain 35,16848.10e23 atoms.
