What is the number of moles in Sodium Chloride?

Answer 1

2, but they can only see at night.

Answer 2

One mole is equal to the atomic mass of the element in grams.
For example, 1 mole of sodium is equal to its atomic mass. If you look at your handy-dandy periodic table, you will see that the atomic mass of sodium is 22.99 grams.
Therefore, 1 mol Na = 22.99 grams
If you have a compound, such as sodium chloride, 1 mole of sodium chloride would equal the formula mass of sodium chloride (22.99 g + 35.45 g = 58.44 g).
Therefore, 1 mol NaCl = 58.44 g
Since the atomic mass of an element is 1 mole, and NaCL is two elements; the number of moles is 2.

Answer 3

The answer to this is going to depend on how much salt you have. We need numbers.

If you have a number of grams of salt, take it and divide by the molar mass of NaCl to get number of moles. The molar mass will be the sum of the atomic weights of Na and Cl in the periodic table - just look those up).

Answer 5

How much you got?

58.5g = 1 mol..... the number of moles you have depends on the mass of Sodium chloride you have.

Answer 6

sodium chloride is NaCl, it contains two elements. in one mole of NaCl there is one mole of sodium and one mole of chlorine.

Answer 7

one mole of any chemical species is equal to its mass.
NaCl is a molecule and therefore
1 mole of NaCl = molecular mass of NaCl
Now, molecular mass of NaCl is the sum of the atomic masses of its constituents
at. mass of Na= 23g
at.mass of Cl= 35.5g
Therefore, mol mass of Nacl= 58.5g
therefore, 58.5g of NaCl= 1 mole of NaCl
your ques is incomplete and you need to specify the amount of salt
for eg. how many moles are present in 117g of NaCl?
ans:58.5g of NaCl= 1 mole of NaCl
thus, 117g of NaCl=117x1/58.5=2 moles

Answer 8

to discover the molar mass of a compound, we ought to record the climate contained in the compound's formulation and confirm the form of atoms of each and every component contained in the formulation. Then, for each component, we ought to seem up the molar mass. as quickly as we've stumbled on the mass contributed by utilizing each and each component for one mole of the compound, the molar mass is calculated by utilizing including those man or woman a lot. answer a million mol Na in NaOH = (a million)22.98977 g/mol = 22.98977 g a million mol O in NaOH = (a million)15.9994 g/mol = 15.9994 g a million mol H in NaOH = (a million)a million.0079 g/mol = a million.0079 g Molar mass of a million mol NaOH = 22.98977 g + 15.9994 g + a million.0079 g = 39.9971 g/mol NaOH 12.
