Determine the mass of an object that has a volume of 88.6 ml and a density of 9.77 g/ml.
Nostrana [21]
Given:
The volume is V = 88 mL
Density, d = 9.77 g/mL

Because mass = volume *  density, therefore the mass of the object is
m = (88.6 \, mL)*(9.77 \,  \frac{g}{mL} )=865.62 \, g

Answer: The mass is 865.2 g  or  0.865 kg
