Considering the definition of molar mass, a salt shaker contains 0.43 moles of sodium chloride.

Definition of molar mass

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

The molar mass of a compound (also called Mass or Molecular Weight) is the sum of the molar mass of the elements that form it (whose value is found in the periodic table) multiplied by the number of times they appear in the compound.

Molar mass of NaCl

In this case, you know the molar mass of the elements is:

Na= 23 g/mole

Cl= 35.45 g/mole

So, the molar mass of the compound NaCl is calculated as:

NaCl= 23 g/mole + 35.45 g/mole

Solving:

NaCl= 58.45 g/mole

Amount of moles of 25 grams of NaCl

Next, you can apply the following rule of three: If by definition of molar mass 58.45 grams of the compound are contained in 1 mole, 25 grams of the compound are contained in how many moles?

[tex]amount of moles=\frac{25 gramsx1 mole}{58.45 grams}[/tex]

amount of moles= 0.43 moles

Finally, a salt shaker contains 0.43 moles of sodium chloride.
