The mass of preheated crucible with cover was 12.1125 g. After the hydrate sample was added, the weight increased to 13.1533 g. After heating the crucible for three times in order to remove hydrate water and bring it to the constant weight the lowest of the three mass measurements was 12.9971 g. 1)What is the mass percent of water in the hydrate? Please report your answer with the correct number of significant figures but without "%" (Canvas will not let you to enter units in this problem). 2) What is the theoretical mass % of water in the hydrate if the salt is BaCl2 x 2H2O?

Why should the selected rule(s) be followed? A residue left on the balance will contaminate the balance pan surface and anything that comes into contact with it afterwards. There may be discrepancies in accuracy between individual balances. Objects at any temperature other than room temperature can create air currents which can affect the balance pan, causing the measured mass to be higher or lower than the true mass. Weighing wet items will cause the displayed mass to be greater than the actual mass of the object.

A pycnometer is a glass flask with a tight fitting glass stopper that can be used to determine the density of an insoluble solid by measuring the volume of water ejected out of the pycnometer when sample of the solid is placed in it. Determine the density in g/cm³ of an unknown metal alloy sample from the following measurements. Assume the density of water is 1.000 g/cm³.Mass of clean pycnometer = 25.151 gMass of clean pycnometer plus water = 42.481 gMass of clean pycnometer plus metal sample = 39.305 gMass of clean pycnometer plus metal plus water = 54.265 g (after ejected water is dried from the outside surface)
A sample sodium is being dried. After 1 hour drying, the mass of the sample was 0.337g. After an additional 30 minutes of drying, the mass of the sample is 0.333g.

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…
Please answer this question as fast as you can please and tahnk you. I will afterwards write an wonderful review on solving the question. Thank you. For each piece of glassware measure the density of water in triplicate (three times). Why repeat the procedure multiple times for each piece of glassware? Running the measurement in triplicate increases the precision of our results and reduces the impact of a single outlier result. The experiment would be too short if you only ran each trial once The first two trials act as practice, and the final trial will give you the true result. Running the measurement in triplicate increases the accuracy of our results and reduces the impact of a single outlier result.
