# A block of wood has a mass of 100 grams and a volume of 150 mL. Water has a density of 1 g/mL. Will the block of wood float or sink?

Float.

#### Explanation:

The formula we are going to use is $\rho = \frac{m}{V}$
=> where $\rho$ is the density in $\frac{g}{m} L$, $m$ is the mass in grams, and $V$ is the volume in $m L$.

$\rho = \frac{m}{V}$
$= \frac{100}{150}$
$= 0.667$

The density of the wood is $0.667$, therefore it will float on water.

Hope this helps :)
