Final answer:
To find the number of moles in 183.3 g of HCl, divide the mass by the molar mass of HCl (36.46 g/mol), resulting in approximately 5.026 moles of HCl.
Step-by-step explanation:
To calculate the number of moles in 183.3 g of HCl, we must use the molar mass of HCl as a conversion factor. The given molar mass of HCl is 36.46 g/mol.
Therefore, we can set up the following conversion:
Number of moles = Mass of solute (in grams) / Molar mass (in g/mol)
This gives us:
Number of moles of HCl = 183.3 g HCl / 36.46 g/mol HCl
By completing this calculation, we find that:
Number of moles of HCl = 5.026 moles (rounded to three significant figures)
