You are asked to determine the mass of a piece of copper using its reported density 8.96g/mL, and a 150-mL graduated cylinder. First, you add 105mL of water to the graduate cylinder, then you place the piece of copper in the cylinder and record a volume of 137mL. Which of the following is the correct mass of the copper reported with the correct number of significant figures? A. 3.5x10^-3 g B. 287g C. 2.9x10² g D. 3.48x10^-3 g E. 286.72g

I need the density (g/mL) for the water column and the isopropyl
alcohol column. With math shown and included please! The question
requires me to show work. If possible, I would also like the
percent error's (with work shown) of the water and isopropyl
alcohol columns. Thank you!

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...
