To find the number of moles in 46g of sodium, you need to divide the mass of the sample by the molar mass of sodium (22.99 g/mol). The calculation is 46g / 22.99 g/mol = approximately 2 moles of sodium.
One mole of Na contains 6.022 x 10^23 atoms of sodium. To find the number of moles in 46g of sodium, you first calculate the molar mass of Na (22.99 g/mol) and then divide 46g by the molar mass to find that it contains approximately 2 moles of sodium.
One mole of sodium hydroxide (NaOH) releases one mole of sodium ions (Na+) when dissolved in water. This is because each formula unit of NaOH contains one sodium ion.
Na2SO4 10.0 grams Na2SO4 (1 mole Na2SO4/142.05 grams)(2 mole Na/1 mole Na2SO4)(22.99 grams/1 mole Na) = 3.24 grams of sodium -------------------------------
1 mole of sodium oxide contains the fewest sodium atoms because it contains 1 mole of sodium atoms. Each of the other compounds (45g of sodium fluoride, 50g of sodium chloride, and 1 mole of sodium nitrate) contains more than 1 mole of sodium atoms.
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.
One mole of Na contains 6.022 x 10^23 atoms of sodium. To find the number of moles in 46g of sodium, you first calculate the molar mass of Na (22.99 g/mol) and then divide 46g by the molar mass to find that it contains approximately 2 moles of sodium.
1 mole
A mole is a counting unit of molecules. Since sodium is an element and is exists by itself one mole of sodium will equal one mole of atoms or 6.02 x 1023 atoms.
One mole of sodium hydroxide (NaOH) releases one mole of sodium ions (Na+) when dissolved in water. This is because each formula unit of NaOH contains one sodium ion.
Na2SO4 10.0 grams Na2SO4 (1 mole Na2SO4/142.05 grams)(2 mole Na/1 mole Na2SO4)(22.99 grams/1 mole Na) = 3.24 grams of sodium -------------------------------
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.
1 mole of sodium oxide contains the fewest sodium atoms because it contains 1 mole of sodium atoms. Each of the other compounds (45g of sodium fluoride, 50g of sodium chloride, and 1 mole of sodium nitrate) contains more than 1 mole of sodium atoms.
When one mole of sodium nitrate (NaNO3) is added to water, it dissociates into one mole of sodium ions (Na+) and one mole of nitrate ions (NO3-). So, one mole of sodium nitrate produces two moles of solute particles in total when dissolved in water.
The formula unit of sodium, as with most other metals, is a single atom. Therefore, one mole of sodium contains Avogadro's Number of atoms, about 6.022 X 1023.
A mole of potassium. Sodium weighs 22.990 g/mol while potassium weighs 39.068 g/mol.
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.
One mole of benzophenone requires one mole of sodium borohydride for reduction to diphenylmethanol.
