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
