Unformatted text preview: date showed that the Pasteur pipette delivers approximately 1 mL of solvent. 3. Density = mass/volume; MW = g/mol; D = 1.32g/mL, 0.52mL = 0.001 mol (1.32g/mL) x (0.52mL/0.001mol) x (1/1000) ANSWER: 0.6864 g/mol 4. To ensure that different solvents are not being mixed within the Pasteur pipette – the pipette itself cannot expel every drop of solvent when squeezed with the human hand. 5. 15 drops = 0.16 g ethyl acetate; (1mL/0.90g) x (0.16g/15drops) ANSWER: 0.01185 mL/drop Conclusion From this lab experiment, I have learned to properly use and deliver solvent using a Pasteur pipette and the importance of using new pipette each time with different solvents. I have also learned to measuring liquids by its weight using the weight balance and by volume using graduated cylinder, beakers, and Pasteur pipette. In conclusion, the Pasteur pipette that was used delivers approximately 1 mL of liquid at its maximum draw....
