The mass of $\text{1000 L}$ of seawater is $\text{1,025,000 g}$, or $\text{1025 kg}$

#### Explanation:

The density formula is:

$D = \frac{M}{V}$,

where:

$D$ is density, $M$ is mass, and $V$ is volume.

In order to use the density formula to solve for mass, multiply the density by the volume.

$M = D \times V$

Mass in Grams

Convert $\text{1000 L}$ to $\text{mL}$.

$\text{1 L=1000 mL}$

1000color(red)cancel(color(black)("L"))xx(1000"mL")/(1color(red)cancel(color(black)("L")))="1,000,000 mL"

Plug in the known values and solve for mass.

$M = 1.025 \text{g"/color(red)cancel(color(black)("mL"))xx1,000,000color(red)cancel(color(black)("mL"))="1,025,000 g}$

Mass in Kilograms

Convert the mass in grams to kilograms.

$\text{1 kg"="1000 g}$
