    The molarity of sodium chloride in sea water is 0.479 M

    Explanation:

    Step 1: Data given

    Mass of NaCl = 28.0 grams

    Molar mass NaCl = 58.44 g/mol

    Step 2: Calculate moles

    Moles NaCl = mass NaCl / molar mass NaCl

    Moles NaCl = 28.0 grams / 58.44 g/mol

    Moles NaCl = 0.479 moles

    Step 3: Calculate molarity NaCl in sea water

    Molarity = moles / volume

    Molarity NaCl = 0.479 moles / 1L

    Molarity of NaCl in sea water = 0.479 mol/L = 0.479 M

    The molarity of sodium chloride in sea water is 0.479 M
