Given:
The volume is V = 88 mL
Density, d = 9.77 g/mL
Because mass = volume * density, therefore the mass of the object is

Answer: The mass is 865.2 g or 0.865 kg
Im pretty sure answer is c :)
Mass = 63.5 grams
density = 0.818 g/mL
D = m / V
0.818 = 63.5 / V
V = 63.5 / 0.818
V = 77.628 mL
hope this helps!
C. The answer is detroyed
