Answer:
171 moles of sodium chloride
Explanation:
Number of moles = mass/molar mass
Molar mass of sodium chloride = 58.5 g/mol
mass of sodium chloride = 10 Kg or 10,000 g
Now, to obtain the number of moles of sodium chloride;
Number of moles = 10,000 g/58.5 g/mol
Number of moles = 171 moles of sodium chloride
