Answer:
3.375 M.
Step-by-step explanation:
- It is known that the no. of millimoles of HCl before dilution = the no. of millimoles of HCl after dilution.
∵ (MV) before dilution = (MV) after dilution.
∴ M before dilution = (MV) after dilution / V before dilution = (0.675 M)(500.0 mL)/(100.0 mL) = 3.375 M.
