Answer:

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"#
