------------------------------------------------ A student weighs a sample of an unknown metal and finds the mass to be 40.15 g. He places 30.0 mL of water into a graduated cylinder. After he drops the metal into the graduated cylinder, the volume increases to 35.5 mL. What is the density of the unknown metal sample?

A. 35.5 g/mL
B. Can't tell from the information given.
C. 0.14 g/mL
D. 40.15 g/mL
E. 7.3 g/mL

A student weighs a sample of an unknown metal and finds the mass to be 40.15 g. He places 30.0 mL of water into a graduated cylinder. After he drops the metal into the graduated cylinder the volume increases to 35.5 mL. The density of the unknown metal sample is (e). 7.3 g/mL.

To determine the density of the unknown metal, follow these steps:

Calculate the volume of the metal:

35.5 mL - 30.0 mL = 5.5 mL.

Calculate the density using the formula density = mass/volume:

density = 40.15 g / 5.5 mL ≈ 7.3 g/mL.

The density of the unknown metal sample is 7.3 g/mL.
