An experiment for the determination of the density of glass beads was performed. Three measurements of a glass bead was performed. The volume yielded 8.11mL, 8.72mL, and 8.01mL. The weight was also measured and the results were recorded as 19.3425g, 19.6812g, and 20.7111g. Calculate the average mass and average volume. The density should yield 2.40g/mL. Calculate the standard deviation for each set of data. Report, using equation 8, the confidence interval for density (use units of density, 95% CI, do not report the average +/- just simply the interval for example 0.55g/mL)!

4. Suppose that a student performed the experiment and calculations perfectly as directed except that, unknown to the student, the balance was not zeroed but weighed 0.100 g too high throughout the experiment. Would the calculated val- ue for the density of the unknown liquid be correct? That is, would it be equal to, higher than, or lower than the true value. Explain your answer in clear and correct English. 16 LABORATORY EXPERIMENTS IN GENERAL CHEMISTRY ed in question 4...

The density experiment involves taking average mass and displaced volume measurements for multiple samples of metal. A student ascertained that the identity of their unknown metal was zinc (d 7.14 g/mL). However, upon consulting their teaching assistant, they learned that the true identity of the metal was copper (d = 8.96 g/mL). What error could the student have made when performing the experiment that would have led to the student's original conclusion? 7.

An experiment on memory was performed, in which 16 subjects were randomly assigned to one of two groups, called "Sentences" or "Intentional". Each subject was given a list of 50 words. Subjects in the "Sentences" group were told to form multiple sentences, each using at least two words from the list, and to keep forming sentences until all the words were used at least once. Subjects in the "Intentional" group were told to spend five minutes memorizing as many of...
