- Give correct detailed Solutionarrow_forwardPerform the calculation and record the answer with the correct number of significant figures. (6.5-6.09) 2.15 = X10 TOOLSarrow_forward(1.7) A student performs an experiment to determine the density of a sugar solution. She obtains the following results: 1.71 g/mL, 1.72 g/mL, 1.71 g/mL, 1.70 g/mL. If the actual value for the density of the sugar solution is 1.50 g/mL, which statement below best describes her results? O Her results are accurate, but not precise. O Her results are precise, but not accurate. O Her results are both precise and accurate O Her results are neither precise nor accurate.arrow_forward
- The answers 0.10 and 0.099 are both incorrect so please don't give me the same answer. Calculate what the answer is with the correct significant figures at the end? How is that and incomplete question? Perform the calculation and record the answer with the correct number of significant figures. (6.5 - 6.03) 4.73 0.099 Incorrectarrow_forwardThis is a practice exercise. i will write down the answer that it says on the book for each problems. i need help on how they got that answer. how many significant figures should the answer in each of these calculations contain? just the significant figures only (A) (14.0) (5.2) Answer: 2. (E) 119.1-3.44. answer: 4 (B) (0.1682) (8.2). Answer: 2 (h) 1.6 + 23 - 0.005. Answer: 2 (C) (160)(33)/4. Answer: 1 (D) 8.2+0.125 Answer: 2arrow_forwardAfter performing the following calculation, the answer should have _____ significant figure(s).arrow_forward
