Sugary Beverages

Today in Chemistry, Mr. Lieberman quickly explained what to do for Part B of the Beverage Density Lab. Part B is nearly identical to Part A except now we were using actual sodas and other juices to caluculate density. By using a pipet to prcisely measure 5ml of our drinks, we then recieved the mass. The Volume was stil 5.00 ml, so once we got the mass, the density could be easily figured out. For those of you that still don't know how to find density, use this formula (D=M/V).
Once all of this was completed, Mr. Lieberman reviewed how to calculate your error %. Refer to Tom M's blog below to get that formula. We must also use our graphs in order to estimate the sugar concentration of our beverages and then use the formula, (Grams of sugar/Volume * Density)*100, in order to recieve the sugar concentration in our beverages.
This should be all the information necessary to complete the lab, which is due tomorrow. Tomorrow is a review day and it's late arrival!
Amar B. is the next scribe, enjoy sleeping in everybody!
