QUESTION ONE

a) Determine the concentration of solution B using solution A.

  1. Calculate the molar mass of solid A (Na₂S₂O₃.5H₂O).

    Molar mass of Na₂S₂O₃.5H₂O = 2(22.99)+2(32.07)+3(16.00)+5(2(1.008)+16.00)=248.20 g/mol2(22.99) + 2(32.07) + 3(16.00) + 5(2(1.008) + 16.00) = 248.20 \text{ g/mol}.

  2. Assume a mass for solid A within the given range (6.0
