( 3 points) A student was doing her pre-lab for the density experiment we did for our first experiment. She was told that the density of the metal sample was 3.57g/ml. She weighed the sample and found that it weighed 14.9g. The pre-lab told her that she would be adding this ingot to 50.0ml of water in a 100ml graduated cylinder and asked her what the volume would read after the ingot was added. Help her out! What should the graduated cylinder show for a final volume after the ingot is added? Oh, Sumona only gives credit in Pre-labs where the significant figures are correct. A. 54.17mL B. 54mL C. 54.174mL D. 54.2mL E. 54.1mL 2. ( 3 points) Believe it or not one of the world's most dangerous animals is the Golden Poison Frog which inhabits the rain forests on the Pacific side of Colombia. This 1 ounce, 1 -inchlong frog has enough Batrachotoxin on its skin to kill 10 fully grown humans. Batrachotoxin has a molar mass of 538.7g/mol. If the average golden frog skin has 1.1510g of Batrachotoxin how many molecules is that? A. 6.02103 B. 1.310H C. 1.2910 D. 1.2981010 E. 1.291017
