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:
Target heart rate is generally expressed as a percentage (usually between 50 percent and 85 percent) of your maximum safe heart rate. The maximum rate is based on your age, as subtracted from 220. At an 85 percent level of exertion, your target would be 145 beats per minute.
