Answer: When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.

Que moralidad hay en una disolución de 35g de KCI diluidos en 250ml de agua
fredd [130]

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
