- Measurements of a patient's temperature are routinely done several times a day in hospitalsDigital thermometers are used, and it is important to evaluate thermometers and select the best one. The accuracy of these thermometers is checked by immersing them in liquids of known temperature. Such liquids include an ice-water mixture at 0.0and boiling water at 100.0C at exactly 1 atmosphere pressure (boiling point with atmospheric pressureSuppose the data shown in the following table were obtained on three available thermometers and you were asked to choose the "best one of the three Which would you choose?

Using a graduated cylinder, she measured out a 45-mLsample of the substance. She then measured the mass of thesample, finding that it weighed 38.5 g. She knew that the substancehad to be either isopropyl alcohol 1density 0.785 g>mL2or toluene 1density 0.866 g>mL2. What are the calculated densityand the probable identity of the substance?

You determine the temperature of your distilled water is exactly 30 degrees celsius. You carefully determined the mass of a clean, dry beaker and found it was 60.1703 g. You pulled the water up to the mark and transferred this to the beaker and found that the new mass was 85.2263 g. What is the actualy volume of the pipet? I tried answering the question above by doing 85.2263 - 60.1703 = 25.056 g I then used 25.056 and multipled it with .995646 (which is the density of water at 30 degrees celsius I believe) The answer I got is 24.947 I am not sure if I am just doing the problem wrong or if it is simply my signifcant figures that are off?
