Responder:
<h2>1.892mol / L
</h2>
Explicación:
La molaridad se define como la relación del mol de una solución por litro de su solución.
Molaridad = Mole de soluto / solución (en litros)
La solución aquí es agua = 250 ml = 0.25L
El soluto es cloruro de potasio (KCl)
Para obtener el mol del soluto, usaremos la fórmula;
Mole del soluto = Masa de KCl / Masa molar de KCl
Masa dada de KCl = 35 g
Para la masa molar de KCl donde K = 39 g / mol y Cl = 35 g / mol
Masa molar de KCl = 39 + 35 = 74 g / mol
Mole del soluto = 35/74 = 0.473 mol
Molaridad = 0.473mol /
0.25L
Molaridad en la solución = 1.892mol / L

It is not continuous because free throws are separate events.
Answer:
The correct answer is herd immunity.
Explanation:
Herd immunity is the resistance against a contagious disease provided by the immune individuals which makes the major part of the population to few susceptible individuals in the community.
So as most of the population is immune to the disease therefore that disease is not able to overpass these immune individuals and the susceptible person is protected indirectly from that contagious disease. By vaccinating most of the people against a disease we can gain herd immunity. So the right answer is herd immunity.
Answer:
