calculate molarity of NaOHin the solution prepared by dissolving its 4g in enough water to form 250ml of this solution ?

  • chemistry - science -

    mols NaOH = grams/molar mass
    The M = moles NaOH/L soln.

  • chemistry - science -

    molarity=moles of solute/volume of whole solution in litres
    so the mass of Na/molar mass of NaOH all divided by .250Litres

    4g/40g divided by .250 litres is .4 M.
    The answer is .4
