Understanding the Terms
* Molarity (M): Represents the number of moles of solute per liter of solution. In this case, the molarity is 0.500 M, meaning there are 0.500 moles of NaCl in every liter of solution.
* Volume (mL): The volume of the solution is given as 22.0 mL.
Calculations
1. Convert mL to L:
* 1 L = 1000 mL
* 22.0 mL * (1 L / 1000 mL) = 0.0220 L
2. Use Molarity to Calculate Moles:
* Moles = Molarity * Volume (in Liters)
* Moles = 0.500 M * 0.0220 L = 0.0110 moles
Answer: There are 0.0110 moles of sodium chloride (NaCl) present in 22.0 mL of a 0.500 M solution.
