Answer:
the volume of sea water is 85866.407 L, necessary to extract 8.0 E4 tons of Mg
Explanation:
- %p/p = 1.3 g Mg / 1000g seawater ) * 100 = 0.13 %
⇒ 8.0 E4 ton Mg * ( 0.00110231 Kg / ton ) = 88.1848 Kg Mg
⇒ 0.13 % = ( 88.1848 Kg Mg / Kg seawater ) * 100
⇒ ( 0.13 / 100 ) = 88.1848 / Kg seawater
⇒ Kg seawater = 88.1848 / 1 E-3
⇒ Kg seawater = 88184.8 Kg
⇒ Vseawater = mass seawater / density seawater
∴ density seawater = 1027 Kg / m³...from literature
⇒ V seawater = 88184.8 Kg / 1027 Kg/m³
⇒ V seawater = 85.866 m³ * ( 1000L / m³ )
⇒ V seawater = 85866.407 L
Almost always, the first way in which biology researchers present the results of their latest research is to discuss the results of previous research that they want to build off of.
Answer:
Explanation:
The element CARBON enters the body in two NATURAL ways.
First is through eating and drinking. Almost all food that we eat contain the element carbon. As the ingested food reaches the digestive system, food is broken down into smaller pieces up until the molecular level. Some molecules are taken into the circulation, while others are excreted down as feces.
Second is by breathing. Certain air molecules contain carbon. One major air molecule is CARBON DIOXIDE. Some molecules are inhaled, but usually, CARBON DIOXIDE should be excreted from the body.
Unnatural ways when CARBON could enter the body is by medical intervention, as in intravenous injections, surgery, etc
