If a saliva sample has a mass of 218. g and a volume of 215. mL, what is its density in
g/mL Be sure your answer has the correct number of significant figures.
Density is calculated by dividing the mass by the volume. In this case, the mass is 218. g and the volume is 215. mL.
Density = mass / volume
Density = 218. g / 215. mL
Density = 1.014 g/mL
Therefore, the density of the saliva sample is 1.014 g/mL. The answer has been rounded to 3 significant figures based on the provided data.
