# A liter of water has a mass of 1000 g. What is the density of water?

Jun 7, 2018

Well, ${\rho}_{\text{density"="mass"/"volume}}$

#### Explanation:

And so we take the quotient...

${\rho}_{{H}_{2} O} = \frac{1000 \cdot g}{1000 \cdot m L} = 1.0 \cdot g \cdot m {L}^{-} 1$

Note that a chemist would typically report a density in $g \cdot m {L}^{-} 1$ or $g \cdot c {m}^{-} 3$ and NOT in $k g \cdot {m}^{3}$...

${\rho}_{\text{water}} = \frac{1000 \cdot g}{1000 \cdot m L} = 1000 \cdot k g \cdot {m}^{-} 3$...
