Mole = Mass/RMM
Ar for Na=23 & Ar for Cl = 35.5
Therefore 1mole = Mass / (35.5+23)
1 mole of NaCl is 58.5g
Mole = Mass/RMM
Ar for Na=23 & Ar for Cl = 35.5
Therefore 1mole = Mass / (35.5+23)
1 mole of NaCl is 58.5g
But that can be misleading. NaCl does not form into molecules (and salts in general do not). If you dissolve 58.5g of NaCl into water, it will dissociate into ions, and there will be 2 moles of particles in solution: 1 mole of Na+ ions, and 1 mole of Cl- ions. Knowing that will be important for calculating various things, such as how many degrees the freezing point will be depressed, when you dissolve so much salt in so much water.
What else can I help you with?
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.
How many grams are in one mole of C5H12?
The molar mass of C5H12 is 72 grams/mole.
How many grams in one mole of ice?
One mole of ice, which is the same as one mole of water, has a molar mass of approximately 18 grams/mol.
How many grams are in one mole of xenon?
The molar mass of xenon is approximately 131.3 grams per mole. Therefore, one mole of xenon contains 131.3 grams.
What is the maximum number of formula units of NaCl in one mole?
The maximum number of formula units of NaCl in one mole is 6.022 x 10^23, which is Avogadro's number. This means that in one mole of NaCl, there are 6.022 x 10^23 formula units of NaCl.
How many grams are in half a mole of NaCl?
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
How much Na is needed to produce a 5 grams of table salt?
5 grams of table salt is 5 grams of NaCl. NaCl has a molar mass of 58.443 grams/mol, so 5 grams would be .0855 mol NaCl. In one mole of NaCl there is one mole of Na, so there would be .0855 mol Na, or 5.235 * 1022 atoms Na.
What is the mass of a mole of NaCl measured by?
The mass of one mole of NaCl is the sum of the atomic weights for sodium and chlorine in grams. The atomic weights are found on the periodic table.
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.
How many moles are in 20.0 grams of NaCl?
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58.5 grams20.0 grams NaCl / (58.5 grams) =.342 moles NaCl
The number of moles in 25 grams of NaCl?
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58 grams 25.0 grams NaCl / (58 grams) = .431* moles NaCl *approximation
How many grams are in one mole of C5H12?
The molar mass of C5H12 is 72 grams/mole.
How many grams of pseudoephedrine are in one mole?
The answer is 165,23 grams.
How many grams of sodium chloride is obtained by the action of chlorine with 4 moles sodium?
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.
How many grams in one mole of ice?
One mole of ice, which is the same as one mole of water, has a molar mass of approximately 18 grams/mol.
How many grams are in one mole of hydrogen peroxide?
36 grams
How many grams are in one mole of xenon?
The molar mass of xenon is approximately 131.3 grams per mole. Therefore, one mole of xenon contains 131.3 grams.
