Question

A graduated cylinder contains 15.75 mL of water. A metal that weighs 32.138 g is added.

The final reading is 38.55 mL. Using the correct number of significant figures, determine the density of the metal = _____ g/mL

First Determine Volume of Metal: Report result to the same number of decimal places as the number with the least number of decimal places. Use this volume in calculation.

Second Determine Density of metal: D=M/V

Answer 1

Displaced volume:

final volume - initial volume :

38.55 mL - 15.75 mL = 22.8 mL

D = m / V

D = 32.138 / 22.8

D = 1.409 g/mL

hope this helps!
