Molarity of 350ml of HCl?

To calculate the molarity of a solution, you need to know the amount of solute (in moles) and the volume of the solution (in liters). In this case, you are given the volume of the solution, but you need to know the amount of HCl in moles.

To determine the amount of HCl in moles, you also need to know the concentration of the HCl solution. The concentration is usually given in units of moles per liter (mol/L) or Molarity (M).

Assuming you have the concentration of the HCl solution, you can use the following formula to calculate the molarity:

Molarity (M) = moles of solute / volume of solution (in liters)

Since you are trying to find the molarity, you need to rearrange the formula:

moles of solute = Molarity (M) × volume of solution (in liters)

However, you're missing the concentration of HCl in your question. Without it, we cannot calculate the molarity. Please provide the concentration of the HCl solution to continue.
