Fresh day MADERNA, let's solve. Step 1: Calculate the molar mass of NaOH. The molar mass of sodium (Na) is 22.99 \, g/mol. The molar mass of oxygen (O) is 16.00 \, g/mol. The molar mass of hydrogen (H) is 1.01 \, g/mol. Molar mass of NaOH = (22.99 + 16.00 + 1.01) \, g/mol = 40.00 \, g/mol Step 2: Calculate the number of moles of NaOH. Moles of NaOH = Mass of NaOHMolar mass of NaOH = 4 \, g40.00 \, g/mol = 0.1 \, mol Step 3: Convert the volume of the solution from milliliters to liters. Volume of solution = 500 \, mL = (500)/(1000) \, L = 0.5 \, L Step 4: Calculate the molarity of the solution. Molarity is defined as moles of solute per liter of solution. Molarity (M) = Moles of soluteVolume of solution in L = 0.1 \, mol0.5 \, L = 0.2 \, M The molarity of the solution is 0.2 M. Send me the next one 📸
