mL

1 answer

The density of an object is calculated by dividing its mass (in grams) by its volume (in milliliters).

Density = mass / volume

Density = 249 g / 247 mL

Density = 1.0081 g/mL

Since the volume is given with 3 significant figures, the density should also be reported with 3 significant figures.

Therefore, the density of the urine sample is 1.01 g/mL.
