1. What is to be expected about the physical appearance when castor oil and water will be mixed?
2. Fill up the missing data (?) in the table and calculate the specific gravity of castor oil. Show your solution in the box provided/
Weight of pycnometer + liquid | Weight of the empty pycnometer | Weight of the liquid | |
Water | 228.68 g | 124.54 g | ? |
Castor Oil | 196.54 g | 124.54 g | ? |
3. What is the use of acetone when determining the specific gravity of oils using a pycnometer?
4. What are some other methods used (aside from the one mentioned in the activity) on how one may measure the density and specific gravity of a liquid?
