Jack measured the mass of an empty evaporating dish and watch glass, and weighed approximately 0.5 g of an unknown solid into the evaporating dish. He then followed the procedure for Lab Exercise 5, and collected the rest of the data in the table below. Please note that row letters correspond to those found on the data sheet that you will use in lab. You will need to refer to this data to answer Questions 13 through 20: A Mass of empty evaporating dish + watch glass 65.362 g B Mass of dish + watch glass + initial solid 65.864 g C Mass of dish + watch glass + carbonate 65.705 g D Mass of dish + watch glass + chloride 65.716 g What was the mass (in grams) of the unknown solid that Jack used in his experiment. Type the numerical answer only in the box below (no units!). Report your answer to the correct number of significant figures.
In our first lab experiment we will be identifying metals by measuring theirdensities and comparing them to known values. Here at NJIT we have a very large and generouslaboratory materials budget, so all sorts of exotic and extremely valuable metals will be providedfor the experiment. Using the values listed below, determine the identity of the metal samples.If the density value determined is not amongst the values below then one of those cheapRutgers samples crept into our stock of metal samples and you should answer “unknown metal”.Note: volume measurements are not very exact. If your density determination is off by 0.1 or0.2 from the known value, that’s probably good enough for an identity. Table in image 4a. You weigh your sample and determine it weighs 71.8 grams. You put the sample into 15.6 mL ofwater and the total volume rises to 22.4 ml. What metal do you have?4b. You weigh your sample and determine it weighs 56.3 grams.

I am slightly confused on how to do this. I think I figured it out but I just want to compare data and take notes on what I have done incorrectly.
Purpose: Learning by teaching is a popular pedagogical tool in education on. The act of learning material to teach to another often leaves the teacher in a stronger position on of understanding and results in higher confidence. Since dimensional analysis is such an important tool for you in your future classes and, more importantly, careers, it has been identified as a major learning objective of this course. You will master the method of dimensional analysis by preparing your own Youtube tutorial on the topic by solving the given problem using dimensional analysis. Problem To Solve: Scenario: you have a very bad head-ache so you run to the pharmacy to grab some medicine and are immediately over-whelmed with your options. You don’t have any allergies or sensitivities to any of the over the counter headache medicines, so you decide to buy the cheapest op on to cure YOUR headache.
