Question #66ab5

Answer 1

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"`
