Calculate the density of a 7.00 × 10^2 g object that has a volume of 98.7 mI. Be sure your answer has the correct number of significant
figures.
To calculate density, divide the mass of the object by its volume.
Density = Mass / Volume
Density = 7.00 × 10^2 g / 98.7 mL
Density = 7.00 g / 0.0987 L (since 1 mL = 1 cm^3 = 0.001 L)
Density = 70.85 g/L
Since the volume was given to only 3 significant figures, we should round the density to 3 significant figures as well.
Therefore, the density of the object is 70.9 g/L.
