-- 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.
