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
Monica because she says it firmly and says she doesn't do drugs. Peter would get asked another day about doing drugs when he feels better and Jeremy could get in a fight with the person who asked him honestly their is no right or better way to say no to drugs its honestly the situation the person and how the person deals with the self in my perspective i would go with Monica <span />
