Compare 1 mole of H2, 1 mole of O2 and 1 mole of F2

likoan [24]

Explanation:

(a) As per the mole concept, one mole of any atom contains $6.022 \times 10^{23}$ atoms or molecules, that is, Avogadro's number of atoms.

Therefore, 1 mole of $H_{2}$ = $2 \times 6.022 \times 10^{23}$ molecules

= $1.2044 \times 10^{23}$ molecules

1 mole of $O_{2}$ = $2 \times 6.022 \times 10^{23}$ molecules

= $1.2044 \times 10^{23}$ molecules

1 mole of $F_{2}$ = $2 \times 6.022 \times 10^{23}$ molecules

= $1.2044 \times 10^{23}$ molecules

Hence, there are equal number of molecules present in the given atoms.

(b) Mass of each given atom will be calculated as follows.

Mass = no. of moles × molar mass

As one molecule of $H_{2}$ contains 2 atoms of hydrogen.

So, mass of 1 mole of $H_{2}$ = $2 mol \times 1.008 g/mol$

= 2.016 g

mass of 1 mole of $O_{2}$ = $2 mol \times 15.999 g/mol$

= 31.996 g

mass of 1 mole of $F_{2}$ = $2 mol \times 18.998 g/mol$

= 37.996 g

Thus, we can conclude that $F_{2}$ has the greatest mass.

Dafna1 [17]

<em>Answer:</em>

The atom have a full valence electron shell.

<em>Explanation:</em>

My question is that why covalent bonds take place?

Every atoms tends to from bond with another atoms in order to get nearest electronic configuration of nobel gases. They become stable when their valence shell become complete. So when covelant bond forms between atoms, share electrons to each other and stabilize themselves.
