If a pharmacist combined 50-mL portions of three syrups having specific gravities of 1.10, 1.25, and 1.32, what would be the specific gravity (to two decimal places) of the combined product? A laboratory utilizes a mixture of 10% dimethyl sulfoxide (DMSO) in the freezing and long-term storage of embryonic stem cells. If DMSO has a specific gravity of 1.1004, calculate the specific gravity, to four decimal places, of the mixture (assume water to be the 90% portion).
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 temperature
Like anatomy and physiology, chemistry may be a somewhat scary subject for you. Think of it this way: Chemistry is simply the study of matter, its composition, structure, properties, and the changes matter may undergo. Your goal in training as a cosmetologist is not to become a scientist, but to develop a comfort level with the basics and an ability to discuss chemistry in relation to your profession. This will increase your credibility significantly with your clients, especially during the consultation process. In the space provided, write how chemistry affects your everyday life.
You are checking the accuracy of a volumetric flask marked 10.00 mL . To calculate the volume of water contained in the flask, you first measure the mass of the empty flask and the mass of the flask filled with water and take the difference. Then, you correct for the buoyancy factor and divide by the density of the water. The result of 8 such measurements is given in the table. Calculate the 95% confidence interval for these measurements with a mean of 10.03.
A 795-centigram sample of borax was placed in a certain volume of water at 25 degrees celsius. After adding the sample, the graduated cylinder was read at 35 mL, where a rise of 2.7 mL was observed. What is the weight (grams) of sample? What was the initial volume (millimeters) of water? What will be the weight of displaced water in grams? What is the specific gravity of the solid? What will be its specific volume?
In our chemistry laboratory class, the formula for surface tension given is y=mg/2(pi) x r x f where y=surface tension, m= mass of the drop, g= gravitational acceleration, pi is 3.1415, r= outer radius of burette, f=correction factor. 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?
