Question

A 210 gram piece of metal has a volume of 81 cm3. What is the density of this metal?

Answer 1

It’s 17,010 g/cm3

Step-by-step explanation:

All your doing is multiplying your numbers together

Answer 2

2.6 g/cm3

Step-by-step explanation:

Density,
`\rho=\frac {m}{v}`

Where m is mass and v is the volume of the object.

Substituting 210 g for m and 81 cm3 for v then

Then,
`\rho=\frac {210 g}{81 cm3}=2.592592593\approx 2.6 g/cm^(3)`
