Question

A granular sample of metal weighs

17 grams. It displaces 7.4 mL of water. What
is the density of the metal?
Answer in units of g/mL.

Answer 1

Mass, Volume and Density

There is a formula that we can use to solve for these variables:

`D=(m)/(V)`

Solving the Question:

We're given:

• m = 17 g
• V = 7.4 mL

⇒ Plug the given values into the equation:

`D=(m)/(V)\\\\D=(17g)/(7.4mL)\\\\D=2.3g/mL`

Answer

The density of the metal is 2.3 g/mL.
