A metal sample has a mass of 227.30 g. When placed in a graduated cylinder, the metal sample displaced 84.2 mL. What is the density of the metal?

Answer 1

Use the density formula. Solve for the desired variable. Plug in the units and solve.

The density formula:

D=m/v

D=density

m=mass

v=volume

D=?

m=227.30 g

v=84.2 mL

D=(227.30 g) / (84.2mL)

D=2.69952494 g/mL

With sig figs:

D=2.70 g/mL

Note:

D=m/v

m=VD

v=m/D
