-- The weight of the liquid and the flask together is  703.55 g.

-- We know that  345.8 g of that is just the weight of the flask.
    So the weight of the liquid alone is    (703.55  -  345.8) .

--  The question told us that the volume of the liquid is 225 mL .

--  The density of the liquid is

             (its weight)
divided by
             (its volume) .

You know the weight and you know the volume, so
you can easily find the density.
