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
They start creating thoughts on how they aren’t ready for the specific challenge or how they aren’t good enough which can cause so much stress
Answer:
The Dietary supplement health and education act does not allowed to Regulating the dietary supplements to be regulated by the FDA before they are marketed.
The probable negative out come of this disease include that unsafe substances can be added to the dietary substances and marketed without listed on label.
FDA must regulate and prove such substances is unsafe restrict it from the market.
False.
