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:
30 minutes
Explanation:
Exercise<u> is an important part of life.</u> It gives you a lot of benefits, such as <em>healthy mind and body.</em> This can be done at any time of the day.
However, there are certain things that you need to consider. For example, if you just woke up in the morning and are in the mood to exercise, you can actually just have some fluid and skip the light meal (that is, if your workout is not that intense).
Nevertheless, <u>you can also eat some light snacks if you want, provided that they are eaten at least 30 minutes before the exercise activity. </u><u>This will allow the food to be digested.</u>
Digestion of food, allows it to fuel your body with energy once you workout.
Thus, it will serve its purpose.
Puberty, menopause, substance abuse, disease and pregnancy are the biggest ones.
