How many moles of sodium are needed to make 3.6 moles of sodium chloride?
One mole of sodium chloride is composed of one mole of sodium atoms. Therefore, 3.6 moles of sodium chloride would require 3.6 moles of sodium.
How many molecules of NaCl are in the 1 M NaCl solution?
It depends on how much solution you have!"1 molar solution" means that 1 litre of the solution contains 1 mole of solute (in this case, Na+ and Cl- ions). Therefore, 1 litre of 1M NaCl will contain 1 mole of sodium chloride. 1 mole is avagadro's number (6.02x1023) of a substance. If you have two litres of solution, obviously, you will have twice this number, for example.Note, though, that there are NO molecules of sodium chloride - sodium chloride is not a molecular substance.
What is the osmolarity of a 0.1 mole sodium chloride solution?
One mole solution of sodium chloride makes 1000 millimole. So 0.1 mole solution of sodium chloride will have 100 millimole in the solution.
In the equation 3Na Plus AlCl30 equals 3NaCl plus Al how many aluminum molecules will be produced if you have 30 molecules of sodium?
If you have 30 molecules of sodium reacting with aluminum chloride (AlCl3), they will produce 10 molecules of aluminum. This is because the balanced equation shows that 3 moles of sodium react with 1 mole of aluminum, producing 1 mole of aluminum.
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.
When one mole of sodium chloride dissociates in water it produces what?
When one mole of sodium chloride dissociates in water, it produces two moles of ions: one mole of sodium ions (Na+) and one mole of chloride ions (Cl-). This is due to the sodium chloride molecule breaking apart into its constituent ions when dissolved in water.
What is the mass of sodium in 11.7 g of sodium chloride?
This question can be answered with the equation n = m ÷ M (where n is the number of mol's, m is te mass in grams and M is the Molar Mass of Sodium Chloride). Now, sodium chloride's molecular formula is written as, NaCl Now if we think of this formula as representing a ratio of elements within the compound, we can see that, NaCl : Cl = 1 mole of sodium chloride molecules : 1 mole of Chloride atoms So, as we know the mol ratio for this molecule, we can establish the mass of sodium in 11.7g of sodium chloride by first calculating the number of moles of Sodium chloride in 11.7g of the substance, so then moles = mass of sodium chloride ÷ Molar mass of sodium chloride = 11.7 ÷ 58.44277 = 0.20019584971759552122529442050745 moles (note that in stochiometry i personally prefer not to round numbers until the end of the question Now by applying this number to the mol ratio, we can calculate the number of moles of sodium in sodium chloride 1 mole of sodium chloride molecules : 1 mole of Chloride atoms =0.20019584971759552122529442050745 : 0.20019584971759552122529442050745 Now that we have established that the number of moles of of sodium in 11.7g of sodium chloride is 0.20019584971759552122529442050745 mol, the mass of sodium in 11.7g of sodium chloride can be calculated with the formula, m = n M = mass of sodium in 11.7g of sodium chloride = 0.20019584971759552122529442050745 X 23 = 4.6045045435046969881817716716713g (all decimal places)
What is Avogadro's number the number of?
The number of elementary entities in a mole of the substance. The elementary entities depends on the particles making up the substance. For example, argon is made of single atoms, so a mole of argon simply contains Avogadro's number of atoms. Water, on the other hand, is made of molecules, so a mole of water contains Avogadro's number of molecules. Now each water molecule, H2O, contains 3 atoms so a mole of water contains 3xAvogadro's number of atoms. Sodium chloride, NaCl, is made of sodium and chloride ions, in a ratio of 1:1. So a mole of sodium chloride contains Avogadro's number of sodium ions, and Avogadro's number of chloride ions. A mole of sodium chloride therefore contains 2xAvogadro's number of ions in total. The number comes from the number of carbon atoms in 12g of carbon-12.
When one mole of sodium chloride dissociates in water it produces?
When one mole of sodium chloride dissociates in water, it produces one mole of sodium ions (Na+) and one mole of chloride ions (Cl-). Each ion carries a single positive or negative charge respectively.
Does 1 mole of sodium chloride and 1 mole of magnesium chloride are equal?
1 mol = 1 mol
How many grams of sodium are needed to produce 5.3 moles of sodium chloride?
molecular formula for sodium chloride = NaClIf the mole (n) for NaCl = 5.3 moles, then the mole of sodium (Na) = 5.3 moles as well. 1 to 1 ratio mass = moles X molar mass m = 5.3 x 22.9 = 121.37 grams of sodium in 5.3 moles of sodium chloride
What is 0.40 moles of sodium chloride in grams?
A mole is not a unit of weight. A mole tells you how many atoms or molecules you have of a given substance (that number being 6.023 x 1023 which is also known as Avogadro's number). So, depending upon what substance you are dealing with, the weight can vary tremendously. A mole of uranium is much heavier than a mole of hydrogen.
