atomic mass OF Na=23 atomic mass of Cl=35.5 now, for calculating molecular mass of NaCl=23+35.5=58.5
Calculate the percent by weight of sodium (Na) and chlorine (Cl) in sodium chloride (NaCl) * Calculate the molecular mass (MM):MM = 22.99 + 35.45 = 58.44 * Calculate the total mass of Na present:1 Na is present in the formula, mass = 22.99 * Calculate the percent by weight of Na in NaCl:%Na = (mass Na ÷ MM) x 100 = (22.99 ÷ 58.44) x 100 = 39.34% * Calculate the total mass of Cl present:1 Cl is present in the formula, mass = 35.45 * Calculate the percent by weight of Cl in NaCl:%Cl = (mass Cl ÷ MM) x 100 = (35.45 ÷ 58.44) x 100 = 60.66% The answers above are probably correct if %Na + %Cl = 100, that is,39.34 + 60.66 = 100.
The molecular mass is the sum of the atomic weights of the elements contained in the molecule. Ex.: mass of sodium chloride (NaCl) = atomic weight of Na + atomic weight of Cl
Salt is a molecular compound. It contains Na+ and Cl- ions in a 1:1 ratio.
Sodium is 39,66583 %, chlorine 60,33417 %; the ratio Cl/Na is 1,521.
The atomic mass of chlorine is 35.5. A chlorine molecule has two chlorine atoms. Therefore its molecular mass is 71u.
Atomic mass Na = 23 g (rounded) Atomic mass Cl = 35.5 g (rounded) Molecular mass NaCl ≈ 58.5 g 13g = 13/58.5 = 0.221 moles
Na= SodiumCl= ChlorineNaCl = Table salt
By definition, one mole would be the same as the atomic mass or molecular mass. You take the number of moles and multiply it by the molecular mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will just be the molecular mass. The molecular mass is the atomic masses of the elements in the compound added together.Na- 23.0Cl- 35.5NaCl- 58.5 grams in one mole
For this conversion you need the atomic masses of the two elements to find the molecular mass of the NaCl.Na: 23.0Cl: 35.5NaCl: 58.5Then, you follow the formula:Mass in grams Ã· Molecular mass = Mass in moles1000 g NaCl Ã· 58.5 = 17.1 moles NaCl
Sodium chloride is dissociated in water: NaCl---------------Na+ + Cl-
Example: sodium chloride, NaCl 1. Search the atomic masses of sodium and chlorine in chemical tables; Na - 22,989 769 28 and Cl - 35,45 (abridged). 2. Calculate the molecular mass of NaCl: Na + Cl = 58,43976928 = 58,44 (abridged) 3. Calculate the percentage of sodium: 58,44 g NaCl--------------22,99 g Na 100 g NaCl----------------x x = 22,99.100/58,44 = 39, 34 % Na 4. Calculate the percentage of chlorine: 100 - 39,44 = 60,56 % Cl
Structural formulae are usually used to describe covalent molecular compounds. It is illogical to use structural formulae to describe ionic compounds because ionic compounds are typically lattice structures. This means that they are electrostatically fixed to one another, and what would normally be considered molecules run together as ions bond to multiple other ions. For example, NaCl would not look like: Na+-Cl- But rather- (Na+)-(Cl-)-(Na+)-(Cl-)- (etc.) (Cl-)-(Na+)-(Cl-)- (Na+)-etc (Na+)-(Cl-)-(Na+)-(Cl-)- (etc.) etc.- etc- etc- etc
Na+ + OH- + HCl --> Na+ + Cl- + H2O
Dissociation is the decomposition of an ionic compound in water solution, forming ions:NaCl----------------------Na+ + Cl-
The molecular weight of NaCl is 58.44g/mol, the atomic mass of Na is 22.99 and the atomic mass of Cl is 35.45 when added together we get 58.44 g/mol.The molecular weight of BaCl2 is 208.233g/mol, the atomic mass of Ba is 137.327 and the atomic mass of Cl2 is (35.453)(2) = 70.906 when added together we get 208.233g/mol
Yes. Example of atomic cation is Na+. Example of atomic anion is Cl-. Example of molecular cation is NH4+. Example of molecular anion is NO3-.
In water? If so - salt solution - the fllowing hydrated ions - H+, OH-, Na+, Cl- plus molecular H2O. Sugar solution - hydrated sugar molecules, molecular H2O and H+ and OH- hydrated ions
Na+Cl are covalently bonded due to the fact Na is in group and Cl is in group 7
--------Cl F-------C--------Cl --------Cl
NaCl---------------â†’Na+ + Cl-
Ionic compounds tend to shatter when struck with a hammer. This is due to the crystal structure formed by an ionic compound, which is basically repeating units of negatively and positively charged ions in some sort of geometric arrangement. When struck, ions of similar charge and pushed next to each other. These ions repel and the whole crystal will then cleave apart along the crystal pattern. example: Left undisturbed NaCl crystal, right struck Na Cl :crys.tal breaks along crystal pattern Na Cl Na Cl Na Cl Cl Na Cl Na Cl Na Na Cl Na Cl Na Cl Na Cl Cl Na Cl Na Cl Na Cl Na Na Cl Na Cl Cl Na Metallic bonds are better pictured as an electron sea, where all the metal atoms that are participating are freely sharing electrons amongst each other. Because of this there are no localized charges to repel each other, making metallic bonds far less susceptible to shattering.
No, while sometimes it can: 2 H2 + O2 --> 2 H2O (molecular) It's not always: Na + Cl --> NaCl (which is ionic)
The chemical symbol for sodium is Na. Amount of Na = mass of sample/molecular mass = 350/23.0 = 15.2mol
This molecule has three Cl atoms and one P atom. Their atimic masses are 35 and 31 respectively. The gram molecular mass for this compound is 31+35x3=136.
