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.

When we are interested in biological energy resources and metabolism, we need to know, among other things the work that an organism has to do to carry out the normal activities of being alive. How much metabolic E must a bird of mass of 153.3 g exert to fly a height of 6.83 m from earth ground? Neglect all the losses due to friction, physiological imperfection and the acquisition of kinetic energy. Us gravity 9.807 m/s2. Answer in _______ J. 4 sig. number normal format (default is n.f.).
