Answer:
27.3699 x 10^23
Explanation:
Just do 4.545 x 6.022 x 10^23
1 mole of any substance = 6.022 x 10^23 molecules.
![4.545 \times 6.022 \times 10 {}^{23}](https://tex.z-dn.net/?f=4.545%20%5Ctimes%206.022%20%5Ctimes%2010%20%7B%7D%5E%7B23%7D%20)
The answer to this would be 3,265,440
hope this helps
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
Answer:
A stimulus is felt by an organism's senses which are sensitive parts of his physiology. ... When any part of an organism or of man's sensory organs is stimulated, a reaction or a response will result. A response is the behavior that is manifested by a living organism which is the result of an external or internal stimulus
