How many pounds of carbon dioxide are emitted of 400 liter pls i need asap
Nookie1986 [14]

884 pounds of carbon dioxide are emitted in 400 litres.

What is a pound?

The pound is defined as the basic unit for weight in the Foot Pound Second (F.P.S) system and is equal to 16 ounces.

To convert a litre measurement to a pound measurement, multiply the volume by 2.204623 times the density of the ingredient or material. Thus, the volume in pounds is equal to the litres multiplied by 2.204623 times the density of the ingredient or material.

One litre of water weighs approximately 2.21 pounds.

So 400 liter = 400 liter x 2.21 pounds

= 884 pounds

Hence, 884 pounds of carbon dioxide are emitted in 400 litres.
