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
Answer:
The correct answer is - option A.
Explanation:
Working Memory is a system for temporarily holding the information or the memory need to carry out the processing and able to deal it with reasoning for decision making or behavior.
This type of memory helps in solving the problem by relating with the prior knowledge or information and utilize it with reasoning and guidance. In this question Janine used her prior knowledge of about sharks and use it to answer the question on basis of that.
Thus, the correct answer is - option A.
