- A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of carbon tetrachloride, diethylamine, methyl acetate, tetrahydrofuran, and acetone. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information:A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet.

Now I searched the internet and it says that the unit for surface tension is kg x m/s^2. The problem is I have grams for the mass of the drop and that the outer radius of the burette is in centimeter while the gravitational acceleration is in meter. What will happen is like this: (1 g x 9.8 m/s^2) / 2 (3.1415) x 0.15 cm x 0.74643 (correction factor no unit) As you can see, if I don't cancel m and cm, the unit will be g x cm x m x s^2. However if change the radius of the burette into meter, it will cancel, the unit will be g x s^2 (missing meter). What can I do to get kg x m/s^2 as the unit for final answer?
- A manufacturer of paint claims that a gallon (3.78 L) of latex paint can cover 365 ft2 of the surface of a wall in a single coating. The paint manufacturer also claims that one single coating of an entire wall will be 3.40 mm thick. Is this a case of false advertising? Yes or No? Elaborate your answer by providing a calculation (handwritten, upload a pdf). You may use the following conversions: 12 in = 1 ft, 2.54 cm = 1 inWhat is the exact value of the density of water (in g/ml) at 25 degrees Celsius? What is the reference standard for solids? What is the environment in assessing apparent density? What is the exact value of relative density of water (in g/ml)? What is the solid sample used to determine the specific gravity using the specific gravity bottle?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?

If either answer is yes, can you give an example?In an experiment to calibrate a 50 ml burette at 30 ⁰C, a student calculated the volume corrections for a series of volumes delivered by the burette and recorded the following data 1. Plot a graph of volume corrections against apparent volumes and briefly describe the nature of the graph 2. If a student used this burette to measure 45ml of water at 30⁰C, what will be the true volume of water delivered at this temperatureThe specific gravity of a patient’s urine sample was measured to be 1.008.
