HI,
A MOLE IS MOLECULAR MASS.
MOLECULAR MASS OF SODIUM IS 23.
HENCE, 1.22 MOLE = 1.22*23 = 28.60
If one atom has a mass of 22.99 amu, and we know how many atoms there are in one mole of a substance (Avagadro's constant) then times the two together.
The mass of one mole is the average Atomic Mass number of the chosen mass units, usually grams, in which the mole is expressed. For sodium, the average atomic mass number is 22.9898.
The mass of 1,22 moles of sodium is 28,047 g.
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.
35.5 grams per mole or 5.90*10^-23 for a single atom
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.
The periodic table states that the molar mass of copper is 63.546 grams per mole. That means that if you have one mole of copper, it will weigh 63.546 grams. One mole is 6.022x1023 (Avogadro's number) atoms. To find the mass of one copper atom in grams, you simply divide copper's molar mass by the number of atoms in one mole. 63.546 / 6.022x1023 = 1.055x10-22 One atom of copper weighs 1.055x10-22 grams.
10.81g This is found by looking at the atomic weight. The atomic weight refers to the mass of a singe atom in units of AMU (atomic mass units) and it also refers to the mass of one mole of the element in grams.
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.
"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.
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.
If the Atomic Mass of an atom is x, then the mass of 1 mole of the atoms is x gram.
You have one mole sodium and one mole chlorine so one mole NaCl will be formed that weight as (23+35.5)=58.5 g
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.
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.
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...
what is the atomic mass of an element : atomic mass is equal to the number of protons and number of neutrons present in an element
The ion sodium is Na + so we have a one to one loss and can just find the atoms of sodium in the mass. 42 grams sodium (1 mole Na/22.99 grams)(6.022 X 1023/1 mole Na) = 1.1 X 1024 atoms of sodium -----------------------------------------now, Every atom of sodium donates one electron to become a sodium ion. So. We have.....1.1 X 1024 .......electrons lost by 42 grams of sodium ionized.
35.5 grams per mole or 5.90*10^-23 for a single atom
