WHAT ARE THE SOURCES OF ERRORS IN DIFFERENTIAL COUNTING?
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.

||| = O MATTER Calculating volume by combining the volume of simple shapes A chemistry student in lab needs to fill a temperature-control tank with water. The tank measures 34.0 cm long by 17.0 cm wide by 14.0 cm deep. In addition, as shown in the sketch below, the student needs to allow 2.0 cm between the top of the tank and the top of the water, and a round-bottom flask with a diameter of 11.5 cm will be just barely submerged in the water. Calculate the volume of water in liters which the student needs. Round your answer to the nearest 0.01 L. Explanation Check 2 cm water X flask 21 OL m stv X 1/3 5 Kirste Ⓒ2023 McGraw Hill LLC.
