Question
Using an automatic delivery pipet, a student in the lab dispenses 356 µL of their unknown liquid into a 10 mL Erlenmeyer flask. The mass of the empty flask was 8.471 g. After the liquid was added, the flask and contents weighed 8.785 g. What is the density (in g/mL) of the liquid?
Expert Solution
Step 1
given, the mass of the empty flask = 8.471 kg
mass of the flak + liquid = 8.785 kg
volume of liquid = 356 µL = 0.356 mL
