Which statement describes a chemical property of water? Under the proper conditions, water will break apart into hydrogen and oxygen gas.
Under the proper conditions, water will break apart into hydrogen and oxygen gas.

Water will dissolve sodium chloride, or table salt.
Water will dissolve sodium chloride, or table salt.

The melting point of water is 0°C.
The melting point of water is 0°C.

Water forms beads on a waxy surface.

Molarity of solution is given as,

                      Molarity  =  Moles / Volume of Solution    (1)

As we are given with mass, so we will expand moles as,

                      Molarity  =  (Mass / M.Mass) / Volume of Solution
Or,
                      Molarity  =  Mass ÷ (M.mass × Volume of Solution)  -- (2)
SO,
      Molarity  =  Unknow

      Mass  =  58.4 g

      M.Mass  =  58.4 g.mol⁻¹

      Volume  =  As it is missing in statement, so we will assume it 1 L

Putting values in eq.

                      Molarity  =  58.4 g ÷ (58.4 g.mol⁻¹ × 1 L)

                      Molarity  =  1 mol.L⁻¹
