Step 1: Calculate the molar mass of NaOH. The molar mass of sodium (Na) is approximately 22.99 g/mol. The molar mass of oxygen (O) is approximately 16.00 g/mol. The molar mass of hydrogen (H) is approximately 1.01 g/mol. Molar mass of NaOH = 22.99 + 16.00 + 1.01 = 40.00 g/mol Step 2: Calculate the number of moles of NaOH. Given mass of NaOH = 7.56 g. Moles of NaOH = MassMolar mass = 7.56 g40.00 g/mol Moles of NaOH = 0.189 mol Step 3: Calculate the molarity of the solution. The volume of the solution is given as 1 litre. Molarity (M) is defined as moles of solute per litre of solution. Molarity = Moles of NaOHVolume of solution (L) = 0.189 mol1 L Molarity = 0.189 M The molarity of the solution is 0.189 M.
