# Susan's classroom has a saltwater fish tank. The volume of the tank is 1890 L, and the density of seawater is 1.03 g/cm^3. What would be the mass of the water in the fish tank?

Multiply the volume with density

#### Explanation:

Density essentially gives the mass of the material per unit volume.

Here density is given as 1.03g/c${m}^{3}$

Which means 1c${m}^{3}$ volume of water has a mass of 1.03 gram

Here the volume of water tank is 1890 L

1 Liter = ${10}^{-} 3$ ${m}^{3}$

Mass of 1890 x ${10}^{-} 2$ ${m}^{3}$ = (1.03g / ${10}^{-} 2$ ${m}^{3}$) x( 1890 x ${10}^{-} 2$ ${m}^{3}$)

Mass = 1946.7 Kg
