Question

A flask containing 9.5 mL of a liquid weight 157.2 g with the liquid in the flask and 148.4 g when empty calculate the density of the liquid in grams over milliliters to the correct number of significant digits

Answer 1

Density = Mass/Volume
Mass = 152.7 gVolume = 9.5 mL
Since the mass gram correspond to the volume mL, then we can apply the formula:
Density = 152.7/9.5 = 16.074 g/mL (Or kg/L)
