The formula unit for this compound has a gram molar mass that is the sum of the gram atomic masses for its two constituent atoms, 22.989 + 35.483 = 58.472. Therefore, 2.1 g constitutes 2.1/58.472 = 0.0359 mole. Multiplying this number of moles by Avogadro's number, which is 6.022 X 1023, gives the number of atoms of sodium, 2.2 X 1022 atoms of sodium.
What else can I help you with?
What is the ions in NaCl?
The ions in NaCl are sodium ions (Na+) and chloride ions (Cl-). In a NaCl crystal lattice, sodium atoms lose an electron to form positively charged sodium ions, while chlorine atoms gain an electron to form negatively charged chloride ions.
What ions are in NaCl?
A sodium ion. Cation. Na+ A chlorine ion. Anion Cl- Forms NaCl, sodium chloride.
What is a chemical equation for the dissociation of a soluble salt in water?
An example is the dissociation of NaCl in water: NaCl (s) -> Na+ (aq) + Cl- (aq). Here, NaCl breaks apart into its constituent ions, Na+ and Cl-, when dissolved in water due to the attraction between the ions and water molecules.
When NaCI dissolves in water does it give ions or molecules or both?
Ions. NaCl is a molecule. And when put in water the polar quality of the water molecules pull apart the na and the cl into ions.
What compound is formed through dissociation?
Dissociation of what? Table salt, for example (NaCl) dissociates into Na+ and Cl- ions in water.
How many moles of Na plus ions are there in a moles of NaCl?
There is one mole of Na⁺ ions for every mole of NaCl. This is because each mole of NaCl dissociates into one mole of Na⁺ ions and one mole of Cl⁻ ions in solution.
Na+ and Cl- are ions formed from?
Na+ + Cl- --> NaCl NaCl = salt.
How many moles of ions are in 1.5 mol of NaCl?
Based on the stoichiometry of NaCl, for every one mole of NaCl there is one mole of Na+ and one mole of Cl-. Therefore, there are 1.5 moles Na+ and 1.5 moles Cl-, totaling 3 moles of ions altogether
How many Na ions are in 4.2 g of NaCl?
To determine the number of Na ions in 4.2 g of NaCl, we need to first calculate the amount of NaCl present. The molar mass of NaCl is 58.44 g/mol. This means that in 4.2 g of NaCl, there are 4.2/58.44 = 0.072 mol of NaCl. Since NaCl dissociates into 1 Na+ ion and 1 Cl- ion, there are 0.072 mol of Na+ ions in 4.2 g of NaCl. To find the number of Na+ ions, you would then multiply the number of moles by Avogadro's number (6.022 x 10^23).
How many composite Na ions are present in a single unit cell of a NaCl crystal lattice?
In a single unit cell of a NaCl crystal lattice, there are six composite Na ions present.
How many sodium ion and chloride ions are present in 30g of Nacl?
30 g NaCl = 0.513 mol NaCl So No. of Na+ ions = 3.088 X 1023 So No. of Cl- ions = 3.088 X 1023
How many sodium ions can be found in 145g of NaCl?
145 grams NaCl (1 mole NaCl/58.44 grams)(1 mole Na +/1 mole NaCl)(6.022 X 1023/1 mole Na +) = 1.49 X 1024 ions of sodium =====================
How many oppositely charged ions are clustered around each Na plus and Cl- ion in a NaCl crystal?
In a NaCl crystal, each Na+ ion is surrounded by six Cl- ions, and each Cl- ion is surrounded by six Na+ ions. This leads to a 1:1 ratio of Na+ ions to Cl- ions in the crystal lattice.
What is the ions in NaCl?
The ions in NaCl are sodium ions (Na+) and chloride ions (Cl-). In a NaCl crystal lattice, sodium atoms lose an electron to form positively charged sodium ions, while chlorine atoms gain an electron to form negatively charged chloride ions.
How many moles of ions are in 2.5 mol of NaCl?
Based on the stoichiometry of NaCl, for every one mole of NaCl there is one mole of Na+ and one mole of Cl-. Therefore, there are 2.5 moles Na+ and 2.5 moles Cl-, totaling 5 moles of ions altogether.
Ions formed from Na plus and Cl- are?
Sodium ions (Na+) and chloride ions (Cl-) are formed when a sodium atom donates an electron to a chlorine atom. This transfer of electrons creates the stable ionic compounds sodium chloride (NaCl).
Do NaOH and NaCl radical?
No, NaOH (sodium hydroxide) and NaCl (sodium chloride) do not have radicals. They are both ionic compounds that consist of ions held together by electrostatic forces. The ions in NaOH are Na+ and OH-, while the ions in NaCl are Na+ and Cl-.
