Mr. Jones' diet should include 1125, 1625 kilocalories coming from carbohydrates.
The Acceptable Macronutrient Distribution Range (AMDR) is the range of macronutrients intake set by dietary professionals of the National Academy of Sciences. The application of this range in our everyday diet can help us achieve a balance between a healthy intake of the necessary macronutrients and a reduced risk of developing chronic disease. According to the AMDR, an adult's intake of carbohydrates should be in between 45-65% of total dietary calories. Since Mr. Jones' total daily intake is approximately 2500 kilocalories, the carbohydrates range should be in between 1125 [(2500*45)/100] and 1625 [(2500*65)/100].
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
