2. In your lab you made four mass measurements using a digital balance and the bar graph shown represents the outcomes for those four measurements. If the accepted mass of the substance being measured is 10.50 g (the dashed line is the average of the four measurements), answer the following questions: 10.5 10 9.78 9.82 9.75 9.80 9.5 1 2 3 4 Trial number A) Are these measurements accurate/precise? B) What kind of error (random/systematic) is exhibited by these measurements? (3) sse

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. You put the sample into 28.9 mL ofwater and the total…
