<u>Answer:</u> A molecule of $ClO_3^-$ has 1 single bond, 2 double bonds and 8 lone pairs.

<u>Explanation:</u>

Lewis-dot structure is defined as the structure which represents the number of valence electrons around the atoms. The electrons are represented as dots.

This structure helps in the determination of bonding electrons and non-bonding electrons.

For the given compound $ClO_3^-$

As we know that chlorine has '7' valence electrons and oxygen has '6' valence electron. The negative charge gets add up in the total number of valence electrons.

Total number of valence electrons in $ClO_3^-$ = 7 + 3(6) + 1 = 26

In $ClO_3^-$ , two electrons of 2 oxygen atoms combine with 2 electrons of chlorine and 1 electron of one oxygen atom combines with 1 electron of chlorine atom.

A lone pair remains on the central atom which is chlorine.

Hence, a molecule of $ClO_3^-$ has 1 single bond, 2 double bonds and 8 lone pairs.

In this problem, Charles' law is applicable since constant pressure with varying volume and temperature are given. Charles' law derived from ideal gas law is expressed as $\frac{ V_{1} }{ T_{1} }= \frac{ V_{2} }{ T_{2} }$ . Subsituting V1=556 cm3, T1=278 K and T2=231 K, V2 or the new volume is 462 cm3.
