HI,
A MOLE IS MOLECULAR MASS.
MOLECULAR MASS OF SODIUM IS 23.
HENCE, 1.22 MOLE = 1.22*23 = 28.60
The amount of energy required to remove one mole of electrons from one mole of sodium atoms is known as the ionization energy. In the case of sodium, the first ionization energy is approximately 495.8 kJ/mol. This energy is needed to remove one electron from a sodium atom to form a sodium cation.
Yes, that is correct. The molar mass of an element is directly proportional to its atomic weight. Lighter atoms have lower atomic weights, which means that one mole of a lighter atom will have less mass compared to one mole of a heavier atom.
35.5 grams per mole or 5.90*10^-23 for a single atom
32 grams, you can find the mass of one mole of any element by looking at its atomic mass eg chlorine has Atomic mass of 35.5 so the mass of one mole of chlorine is 35.5 grams.
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.
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.
Sodium has an atomic mass of 22.99. Therefore 1 mole of it weighs 22.99 grams. Similarly a mole of bromine weighs 79.9 grams.A mole of sodium bromide - NaBr - contains 1 mole each of sodium and bromine (note that this is not true for all chemical salts) and so 1 mole of it weighs 102.89 grams.
"How much" isn't incredibly specific; what exactly is the measurement?The chemical formula for table salt (sodium chloride) is NaCl - one atom of sodium and one atom of chlorine. So if we're measuring number of atoms, there is 50% sodium and 50% chlorine in one molecule.If we're measuring mass, that's a bit different. The mass of one mole of sodium is about 23.0 grams and the mass of one mole of chlorine is about 35.5 grams. Since both are in equal amounts, we can use percentages and it will still apply to one molecule. One mole of sodium chloride would therefore be 58.5 grams (35.5 + 23.0).23.0 grams of that 58.5 is sodium, so 39.3% of one mole or one molecule is sodium by mass.
If the Atomic Mass of an atom is x, then the mass of 1 mole of the atoms is x gram.
One formula mass of the salt sodium chloride.
A mole of an element or compound is 6.022 x 1023 (Avogadro's constant) molecules of that substance. This number is the number of molecules it takes for an amount of substance to have a mass in grams the same as its molecular mass: carbon has a molecular mass of 12, so 6.022 x 1023 (one mole) carbon atoms have a mass of 12 grams. The molecular mass of sodium is 23 (22.989) so one mole of sodium has a mass of 23 grams. Sodium chloride has a molecular mass of 58.44 so a mole of NaCl is 58.44 grams. One mole of sodium will make one mole of sodium chloride. Na + Cl => NaCl So four moles of sodium will make four moles of sodium chloride. 4Na + 4Cl => 4NaCl Four moles of NaCl has a mass of 4 x 58.44 = 233.76 grams.
The molar mass of an element corresponds to the atomic mass of the element (found on the periodic table). The atomic mass of Sodium-Na is 22.990 g, which is also the molar mass of Na. So for 1 mole of Na, there are 22.990 grams of Na. If we had 3 moles of Na, then we would simply multiply the molar mass by 3.
To find the number of hydrogen atoms that make up the same mass as one sodium atom, you need to compare the atomic masses. A sodium atom has an atomic mass of 23 daltons, while a hydrogen atom has an atomic mass of 1 dalton. Therefore, 23 hydrogen atoms make up the same mass as one sodium atom.
The molar mass of sodium chloride is 58.44 g/mol. To find the mass of sodium chloride formed, you need to compare the moles of sodium and chlorine to determine the limiting reactant. Calculate moles of sodium and chlorine, determine limiting reactant, and use stoichiometry to find mass of sodium chloride formed.
The amount of energy required to remove one mole of electrons from one mole of sodium atoms is known as the ionization energy. In the case of sodium, the first ionization energy is approximately 495.8 kJ/mol. This energy is needed to remove one electron from a sodium atom to form a sodium cation.
mass of one mole of oxygen atom is 16 grams. atomic weight of any atom is equal to mass of 1 mol of that atom...
Yes, that is correct. The molar mass of an element is directly proportional to its atomic weight. Lighter atoms have lower atomic weights, which means that one mole of a lighter atom will have less mass compared to one mole of a heavier atom.
