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

I hope this helps.
Answer:
Secondary
Explanation:
Prevention techniques are divided into 3 broad categories known as the primary , secondary and tertiary prevention techniques.
Primary prevention deals with prevention of the disease from occurring in the first instance.
Secondary prevention minimizes the severity of the disease or injury once it has occurred. This can include health screenings such as mammograms, and colonoscopies for those in the appropriate age/risk category.
Tertiary technique prevent the disease already had by the individual from getting worse and making sure the symptoms are minimal.
