# Comparing the denseness of metals

﻿Comparing the Density of Metals

Issue: What is the result of changing the type of metal on its thickness?

Hypothesis: If a different steel type is used, then the density will change.

Materials:

4 metal trials

Balance

40 ml managed to graduate cylinder

Normal water

Paper towels

Device:

Pre-Lab Inquiries:

1 . Can be the method to calculate density?

D = Meters / Versus

installment payments on your What are the units intended for density?

g/mL, g/L, mg/mL, g/cm3

3. A sample of metal has a mass of 85. six grams and a amount of 12. one particular mL. Exactly what is the denseness of metallic x? Presented:

M sama dengan 85. 6th g

V = 12. 1 milliliters

D sama dengan?

D sama dengan M as well as V

sama dengan 85. six / 12. 1

sama dengan 7. 07438016529 g/mL

Therefore , the thickness of steel x is approximately 7. 074 g/mL.

4. A material bar has a density of 19. several g/mL and a mass of 55 g. What's the volume in the bar? Provided:

M sama dengan 50 g

V sama dengan?

D = 19. several g/mL

V = Meters / G

= 55 / 19. 3

= 2 . 59067357513 mL

Therefore , the volume in the bar is about 2 . 591 mL.

Treatment:

1 . Select one of the 4 metal samples

installment payments on your Use the equilibrium to gauge the mass of every sample for the nearest 0. 01 g. Record the masses inside the data stand. 3. Complete the managed to graduate cylinder 50 percent full of water. Record the volume to the closest 0. one particular mL. 4. Carefully put in the steel sample with out splashing virtually any water Record the volume with the water plus the metal test. 5. Duplicate for each with the metal trials.

6. Dry out the metallic samples.

six. Make sure the balance is still left as you located it.
