To find the molarity of the methanol solution, we need to follow these steps:1. Calculate the number of moles of methanol.2. Divide the number of moles by the volume of the solution in liters.Given information:- Mass of methanol = 25 g- Volume of the solution = 3.5 L- Molar mass of methanol = 32 g/molStep 1: Calculate the number of moles of methanol.Moles of methanol = Mass of methanol / Molar mass of methanolMoles of methanol = 25 g / 32 g/molMoles of methanol = 0.78125 molStep 2: Calculate the molarity of the methanol solution.Molarity = Moles of methanol / Volume of the solution in litersMolarity = 0.78125 mol / 3.5 LMolarity = 0.22464 MRounding the answer to 2 decimal places, the molarity of the methanol solution is 0.22 M.
