Explanation / Answer

Molarity = #of moles of substance / volume of solution inliters = molar concentration 1) molar mass of NaOH = 40 g/mol    #moles = 60g/40(g/mol) = 1.5    Volume = 0.5 L    Molarity = 1.5/0.5 = 3M 2)    #moles = 10    Volume = 5 L    Molarity = 10/5 = 2M 3) #moles = 0.26    Volume = 1 L    Molarity = 0.26/1 = 0.26M 4)Molarity = 0.250    V = 0.350 L    #moles = Molarity * Volume = 0.25 * 0.35 =0.0875 moles    Volume = 1 L    Molarity = 0.26/1 = 0.26M 4)Molarity = 0.250    V = 0.350 L    #moles = Molarity * Volume = 0.25 * 0.35 =0.0875 moles
