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

Use your context clues to determine.
Answer:
1.Soybeans. White beans. Some fish, like sardines, salmon, perch, and rainbow trout. Foods that are calcium-fortified, such as some orange juice, oatmeal, and breakfast cereal. 2.Vitamin C, also known as ascorbic acid, is necessary for the growth, development and repair of all body tissues. It's involved in many body functions, including formation of collagen, absorption of iron, the proper functioning of the immune system, wound healing, and the maintenance of cartilage, bones, and teeth 3.Osteoporosis is a bone disease that occurs when the body loses too much bone, makes too little bone, or both. As a result, bones become weak and may break Explanation:
Answer:
The eccentric contraction can generate up to 50 percent greater tension than the concentric. This is why the eccentric contraction is so powerful not only in controlling and stopping movement, but also in generating sufficient tension in the muscles in order for them to contract explosively.
Hope this helps, have a great day/night, stay safe
I believe it is A and C. :^) Hope this helps!
