Which type of skin glands are most affected by the hormonal changes that occur during puberty?
Anna [14]

Apocrine sweat glands  are most affected by the hormonal changes that occur during puberty.

What is puberty ?

Between childhood and adulthood, puberty is a time of rapid growth, the emergence of secondary sexual traits, the attainment of fertility, and significant psychological changes. Although the order in which pubertal changes occur is fairly predictable, their exact time varies greatly.

At puberty, sex hormones stimulate the apocrine sweat glands, which then begin to work. In the groin and axilla, they are linked to hair follicles. The thick, protein-rich substance has no smell at first but may acquire one after coming into contact with germs.

There are 258 g of MgCl2/liter. What is the molarity of the solution?
Zolol [24]

Taking into account the definition of molarity, the molarity of the solution is 2.7098 moles of MgCl₂/liter.

<h3>Definition of molarity</h3>

Molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

molarity= number of moles÷ volume

<h3>Molarity of the solution in this case</h3>

In this case, you know that the molar mass of MgCl₂ is 95.21 g/mole [molar mass is the amount of mass that a substance contains in one mole.]

You can apply the following rule of three: If by definition of molar mass 95.21 grams are contained in 1 mole, 258 grams are contained in how many moles?

amount of moles= (258 grams× 1 mole)÷ 95.21 grams

<u><em>amount of moles= 2.7098 moles</em></u>

Replacing in the definition of molarity:

258 g of MgCl₂/liter= <u><em>2.7098 moles of MgCl₂/liter</em></u>

<em />

Finally, the molarity of the solution is 2.7098 moles of MgCl₂/liter.
