Use the equation d=m/v
your mass or "m" is 78 g
your volume or "v" is 60mL
if you plug those values into the equation it will look like this:
d=78/60
d=1.3g/mL should be what you come up with
It says cut it in half so the density would become 4g/mL and the Volume would become 5mL
It should be b. or c. my guess is b. because molecules are small. so i think it’s b. (im not entirely sure though)
