How many atoms of Mg are present in 97.22 grams of Mg?
Lostsunrise [7]

Answer: Option (b) is the correct answer.

Explanation:

It is given that mass of Mg is 97.22 g and it is known that molar mass of Mg is 24.305 g/mol.

So, calculate the number of moles as follows.

          No. of moles = \frac{mass given in grams}{Molar mass}

                                 = \frac{97.22 g}{24.305 g/mol}  

                                 = 4 mol

Also, it is known that 1 mole has 6.023 \times 10^{23} atoms/mol. Therefore, calculate the number of atoms in 4 mol as follows.

               4 mol \times 6.023 \times 10^{23} atoms/mol

               = 24.08 \times 10^{23} atoms

or,            = 2.408 \times 10^{23} atoms

Thus, we can conclude that there are 2.408 \times 10^{23} atoms in 97.22 grams of Mg.

mojhsa [17]

Explanation:

The cleansing action of soaps is predicated on the nature of soaps as we have it.

  • A soap has the ability to remove dirt from materials.
  • The cleansing action of a soap is related to the structure of its molecule.
  • A molecule of soap has dual structure with polar head that is water loving and a long hydrocarbon tail which is hydrophobic.
  • The structure enables soap molecules to emulsify an organic dirt present on a fabric in water.
  • The soap causes the suspension of tiny oil droplets in the aqueous medium.

How are oxygen and<br> water molecules different<br> from argon and neon<br> molecules?
Ghella [55]

Answer:Argon is an element on the periodic table. It is a member of the noble gasses, meaning that it is a monoatomic pure gas. In other words, argon gas particles are simply pure single atoms of argon. ... Finally, water is a polyatomic molecule H2O composed of two atoms of hydrogen and one atom of oxygen.
