# The density of mercury is 5,427 kg/m^3. If the density of water is 1.0 g/mL, will mercury float or sink in water?

Are you sure you have got your density right? Anyway, mercury will DEFINITELY sink in water.

#### Explanation:

The density, $\rho$, of mercury $=$ $13 , 593 \cdot k g \cdot {m}^{-} 3$; it is $13.6 \cdot g \cdot c {m}^{-} 3$ in more accessible units. Anyway, mercury metal is pretty dense stuff. If you ever found a pool of mercury, you could toss a big boulder in, and jump on the boulder, and surf on it.
