The formula mass of NaCl is 23.0 + 35.5 = 58.5Amount of NaCl = 60/58.5 = 1.03mol
So there is 1.03 moles of NaCl in a 60 gram pure sample.

If a mixture of sand and salt weighing 74 grams is composed of 48 percent salt How many moles of salt are there?
48 percent of 74 is 35.52, so there are 35.52 grams of salt. The molar mass of salt (NaCl) is 58.443 grams per mole, giving .608 moles of salt.
How do you calculate number of moles in 1 teaspoon of salt?
First weigh the salt, preferably in grams. To finish the question let pretend it weighed 2g. Next calculate the molar mass of salt (NaCl). Na = 22.98976928 g/mol plus Cl = 35.45 g/mol so NaCl = 58.43976928 g/mol. If 58.43976928 is 1 mol, 2 g is: 2/58.43976928 = 0,034 moles.
How many atoms of sodium and chlorine are in table salt?
Table salt is Sodium Chloride (NaCl) - each molecule has one atom of sodium and one of chlorine. The rough number of atoms can be calculated from the total weight of the salt. NaCl weighs approximately 58g/mol and 1mol is approximately 6*1023 atoms, so the number of mollecules in a weighed sample of pure table salt is (6*1023)/58=0.103*1023W where W is the weight in grams. In one gram of NaCl, there are 10.3 billion trillion molecules and twice as many atoms split half Na and half Cl.
Which salt contains only ions?
Table salt also known as sodium chloride or NaCl is an example of ionic bonding as the ions Na+ and Cl- react in the equation: 2 Na(s) + Cl2(g) 2 NaCl(s), in which 2 moles solid Sodium and 1 mole of Chlorine react to form the solid product NaCl in effect.
How many hydrogen atoms are in salt?
Common table salt is Sodium Chloride ( NaCl ) and has no hydrogen atoms.
How many grams of NaC1 are needed to make1.00 liter of a 3.00M NaC1 solution?
Molarity = moles of solute/volume of solution. 1 liter = 1000 millilitetrs 3.00M = X Moles/1000ml = 3000 millimoles, or 3 moles NaCl 3 moles NaCl (58.44g NaCl/1mol NaCl ) = 175.32 grams needed. About 4/10 of a pound of salt.
How many moles of table salt are in a box that has 117 grams of salt?
roughly a mole is a unit of measurement used in chemistry to express amounts of a chemical substance, defined as an amount of a substance that contains as many elementary entities as there are atoms in the atomic weight of the substance in grams.Sodium has an atomic weight of 22.99Chlorine has and atomic weight of 35.45NaCl has a molecular weight of 58.44Therefore a mole of NaCl would weigh 58.44 grams117 grams is therefore roughly equal to 2 moles of table salt.
If a mixture of sand and salt weighing 74 grams is composed of 48 percent salt How many moles of salt are there?
48 percent of 74 is 35.52, so there are 35.52 grams of salt. The molar mass of salt (NaCl) is 58.443 grams per mole, giving .608 moles of salt.
What is equivalent weight of a salt?
It depends on the salt. However, common table salt NaCl is 58.5
How do you make 2 molarity solution of NaCl?
Two moles of sodium chloride is equivalent to 116,88 (rounded) g.The molar mass of NaCl 58.5 grams per mole. 117 grams of salt is equivalent to two moles. Dissolve this much of salt in exactly 1L of distilled water in a volumetric flask to prepare 2M NaCl.
What is NaCl and how many atoms does it have?
NaCl is the formula unit of sodium chloride (halite, rock salt, table salt, plain salt, common salt, edible salt etc.). NaCl has 2 atoms in the formula unit.
If you dissolve 3.00g of salt in water what are the number of moles of sodium ions dissolved?
0.051 molesWe know the molecular weight of NaCl is 58.443 g/mol and that the formula for the dissociation of salt in water looks like this:NaCl (aq)-->Na+ + Cl-So we can see that there is a one to one mole ratio between NaCl and sodium ions. All we have to do to find the moles of ions is3.00g * 1mol NaCl/58.443 g NaCl = 0.051 mol NaClFrom here we apply the ratio of 1 mol NaCl : 1 mol Na+ (though, since the ratio is one, it's not really necessary in this case):0.051 mol NaCl * 1 mol Na+/1mol NaCl = 0.051 mol Na+
What is the equations for how many molecules are in 3 moles of NaCl?
Sodium chloride is an ionic crystalline salt, and does not form molecules. One unit of sodium chloride is called a functional unit. It is the lowest whole number ratio of ions represented in an ionic compound. 1 mole = 6.022 x 1023 formula units of NaCl 3 moles NaCl x 6.022 x 1023 formula units/mole = 1.8 x 1024 formula units of NaCl
What weights out 120g of sodium chloride?
The answer to the question is 120 grams of water :)
How do you calculate number of moles in 1 teaspoon of salt?
First weigh the salt, preferably in grams. To finish the question let pretend it weighed 2g. Next calculate the molar mass of salt (NaCl). Na = 22.98976928 g/mol plus Cl = 35.45 g/mol so NaCl = 58.43976928 g/mol. If 58.43976928 is 1 mol, 2 g is: 2/58.43976928 = 0,034 moles.
What is salt and NaCl?
Table salt (common salt, edible salt, rock salt, halite) is sodium chloride - NaCl.
