Answer:

0.088mole

Explanation:

Given parameters:

Mass of the compound  = 5.125g

Unknown:

Number of moles  = ?

Solution:

To solve this problem, we need first find the molar mass of the given compound.

Molar mass of NaCl  = 23 + 35.5 = 58.5g/mol

So;

 Number of moles  = [tex]\frac{mass}{molar mass}[/tex]   = [tex]\frac{5.125}{58.5}[/tex]    = 0.088mole
