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
The answer for what if you don't have anything on here.?
What? Lol can you rewrite this?
Answer:
The correct answer would be - the jaw thrust maneuver.
Explanation:
The jaw thrust maneuver is the maneuver that is often used for the patients who are suspected to have a cervical spine injury to prevent obstructing the airway entrance to the trachea in the injured patient.
It is performed by placing middle and index fingers to push the posterior part of the lower jaw physically and the chin is pushed down to open the mouth using thumbs so the mandible gets displace and airway clear by pulling the tongue out.
Thus, the correct answer is - the jaw thrust maneuver.
