The mass of "1000 L" of seawater is "1,025,000 g", or "1025 kg"

Explanation:

The density formula is:

D=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=DxxV

Mass in Grams

Convert "1000 L" to "mL".

"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"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.

"1 kg"="1000 g"

1,025,000color(red)cancel(color(black)("g"))xx(1"kg")/(1000color(red)cancel(color(black)("g")))="1025 kg"
