An irregular piece of the metal is found to weigh 87.4g. It is then placed into a graduated cylinder that contains some liquid. The liquid in the cylinder has an initial volume of 18.46 ml. After the metal was added and the liquid's level rises to 24.14 mL afterward. What is the density of this piece of metal in g/mL units? Enter a number without units.

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...

i dont understand why the molecular weight i calculated
(42.012 g/mol) for my unknown liquid (acetone) is less than the
actual molecular weight (58.08 g/mol). what errors could i have
made in my lab that would account for the difference.
