If a urine sample has a mass of 249. g and a volume of 247. mL, what is its density in
g
-? Be sure your answer has the correct number of significant figures.
mL
mL
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.
