II. Calculation. Provide a solution to the answer and observe Significant figures. Each question is 10 pts. 1. A student wants to know the density of a liquid but he has no appropriate equipment on hand. He crafted a cylindrical container with a height of 300 inches and a diameter of 25 inches. The mass of this container as he measured in three different trials was 3.567kg, 3601g, and 3.605678kg. Now, he poured the unknown liquid into the container and obtained the mass of 6.703 kg, 6.69995kg, and 6708 grams. What is the Volume of the Container? Mass of the container? What is the density of the liquid? 2. A cylindrical glass bottle 21.5 cm in length is filled with cooking oil of density 0.953 g/mL. If the mass of the oil needed to fill the bottle is 1360 g, calculate the inner diameter of the bottle. 3. Indicate the number of protons, neutrons, and electrons in each of the following species: 63 15N, S. Cu, 34 Sr. 16 38 130 56Ba, 74 186W 202 80 28 Hg III.
