Cevap

To find the concentration of HCl in the solution, we need to use the formula: First, we need to calculate the moles of HCl. The molar mass of HCl is 36.46 g/mol. Now, we can calculate the concentration: Therefore, the concentration of HCl in the solution is 0.0350 M, which corresponds to option B.
