Answer
(a) $247.8cm^3$
(b) $608g$
Work Step by Step
$(a)$
We start by finding the weight of the water by subtracting the weight of the empty flask from the weight of the full flask.
$489.1g - 241.3g = 247.8g$
Now we multiply our volume by the given density of water $(d = 1.00 g/cm^3)$ to find the volume.
$247.8g * \dfrac{1cm^3}{1.00g}$
$$247.8cm^3$$
$(b)$
To find the weight of a flask of chloroform, we multiply the volume by the density $(d = 1.48 g/cm^3)$ and remember to add the weight of the empty flask.
$247.8cm^3 * \dfrac{1.48 g}{cm^3} + 241.3g$
$$608g$$
