Using a graduated cylinder, you measure out 250 mL ethanol, which has a density of 0.789 g/mL You transfer this to a previously tared beaker and measure the mass. Repeating this process three times, you obtain the following measurements: • 195.31 8 • 194.78 8 • 194.62 g Report a calculation that indicates the accuracy of the data shown above. (Blank #1) Report a calculation that indicates the precision of the data shown above. (Blank #2) Based on your calculations for accuracy and for precision, do you think any errors occurred in obtaining the measurements? Explain your answer in 1-2 sentences. (Blank #3) Answer for blank # 1: Answer for blank # 2: Answer for blank # 3:

In lab you report a measured volume of 128.7 mL of water. Using significant figures as a measure of the error, what range of answers does your reported volume imply? Explain.
Question 6- Sprite gems are used in the game to revive your character. You need to determine how much space they will take up in your bag. If these gems have a density of 35.4 g/cm3, what will be the volume (mL) of 0.160 kg of gems? (you may need to use a special period table to answer the questions, the table is attached in the images below, also please show all of your work so I can understand going forward.)
the question asks to convert it to Japanese yen, I did so and wasn't sure what the sig figs should come out to be, I figured it to be four sig figs because when finding the mass in grams, we multiply by 10.49 which has four sig figs and I carried it through to the end, reaching 2.1935x105 Japanese Yen. Is this correct in terms of answers AND in terms of significant figures?
A general chemistry student found a chunk of metal in the basement of a friends house. She measured the mass of the metal to be about 189.0 g. Then she dropped the metal into a graduated cylinder containing 25.0 mL of water, and the water level rose to 43.0 mL. Of the following metals, which one is most likely:
please help with this 1) Sally Leadfoot was pulled over on her way from Syracuse to Ithaca by an officer claiming she was speeding. The speed limit is 65 mi/hr and Sally had traveled 97 km in 102 minutes. How fast was Sally’s average speed? Does she deserve a ticket? question2) b) One sphere has a radius of 5.10 cm; another has a radius of 5.00 cm. What is the difference in volume (in cubic centimeters) between the two spheres? Give the answer to the correct number of significant figures. The volume of a sphere is (4/3)πr3, where π = 3.1416 and r is the radius.
A student measures a block to weigh 127.95 grams what would this mass be in milograms with the correct number of significant figures. I know its 127,950 miligrams but 127.95 only has 5 significant figures but 12795 is just not right either. Would it be 127,950.?
The beakers shown below have different precisions. a. Label the amount of water in each of the three beakers to the correct number of significant figures. Is it possible for each of the three beakers to contain the exact same amount of water? If no, why not? If yes, did you report the volumes as the same in part a? Explain. Suppose you pour the water from these three beakers into one container. What should be the volume in the container reported lo the correct number of significant figures?
