The number of moles of sodium chloride in a 321.8 g sample is 5.5 moles. Details about number of moles can be found below.
The number of moles of a substance in a particular mass of that compound can be calculated as follows:
no of moles = mass ÷ molar mass
molar mass of NaCl = 58.5g/mol
No of moles of sodium chloride = 321.8g ÷ 58.5g/mol
no of moles = 5.5 moles
Therefore, the number of moles of sodium chloride in a 321.8 g sample is 5.5 moles.
