answer each and every question in one hour please and make sure all the solution is correct.

Post-Lab Questions: 1. Does your experimental density of the metal sample agree with the true value? If no, give reasons for the discrepancy. Do not include operator errors. 2. Does your experimental density of the unknown liquid agree with the true value? If no, give reasons for the discrepancy. Do not include operator errors. 3. What is the density in g/mL of a ball that has a mass of 22.1 ounces and a diameter of 2.04 inches? Will it float if placed in a bucket of water? The answer is "no." Provide the calculations to prove this and explain in full sentences. 4. If there were air bubbles trapped under the metal pellets in Part II when you recorded its volume, would that give you an experimental density that is too high or too low? Explain. Would this be considered instrumental, method or operator error? Explain. 5. If you were to mix your unknown liquid in Part III with water, would you expect it to float or sink? Explain.
