How many grams of magnesium(Mg, 24.30 g/mol) are in 7.43×10^22 atoms Mg?

Answer : The mass of magnesium is, 2.99 grams.

Explanation :

As we know that 1 mole of magnesium contains atoms

And, 1 mole of magnesium has 24.30 g

So, we can say that:

As, atoms of magnesium present in 24.30 gram of magnesium

So, atoms of magnesium present in gram of magnesium

Therefore, the mass of magnesium is, 2.99 grams.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
