Answer: So basically we have to know does the material's characteristics/compositions affect its density?

Explanation: Density is defined as the ratio of the mass of a material to its volume at a specific temperature and pressure. The Density of material is changed by changing its mass to volume ratio or by changing its temperature or by changing its pressure, the density of material changes. The Density of material is changed by changing its mass to volume ratio or by changing its temperature or by changing its pressure, the density of material changes. From the above description, it can be inferred that a material's composition or chemical characteristics may remain unchanged if density changes by changing the pressure or temperature of the material.

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.

Variation in a trait is a required condition for natural selection to act on a population for that trait. Assuming a population
Sveta_85 [38]

Answer:

I) Sexual reproduction

II) Mutation

Explanation:

Variations refer to the difference observed within organisms of the same species. Variation are introduced into a population by:

- new genetic combinations that occur during sexual reproduction (i.e during meiosis)

- mutations, spontaneous changes that occur in genes and chromosomes.

What is human fetal development? I need simple definition
Elena-2011 [213]
The development of the human embryo follows fertilization, and continues as fetal development. By the end of the tenth week of gestational age the embryo has acquired its basic form and is referred to as a fetus. The next period is that of fetal development where many organs become fully developed.
