Pycnometers are generally available for laboratory use in volumes ranging from 1 mL to 50 mL. Pycnometers have fitted glass stoppers with a capillary opening to allow trapped air and excess fluid to escape. • Q1. A 50 mL pycnometer is found to weigh 120 g when empty, 171 g when filled with water, and 160 g when filled with an unknown liquid. Calculate the specific gravity of the unknown liquid. • Q2. A specific gravity bottle weighs 23.66 g. When filled with water, it weighs 72.95 g; when filled with another liquid, it weighs 73.56 g. What is the specific gravity of the liquid?
