Question

the number of ions present in 0.2 mole of sodium chloride is
1)0.2
2)0.8
3)0.4
4)0.6
please say with correct process

Answer 1

0.2=so^4
0.2=32+16*4
0.2=32+96
0.2=96
no. of moles=0.2/96=0.2

Answer 2

Answer: The correct answer is Option 3.

Explanation:

Sodium chloride is an ionic compound. The ionization of sodium chloride will yield:

$NaCl\rightarrow Na^++Cl^-$

By Stoichiometry of the reaction:

1 mole of sodium chloride produces 2 moles of ions.

So, 0.2 moles of sodium chloride will produce = $\frac{2}{1}\times 0.2=0.4$ moles of ions.

Hence, the correct answer is Option 3.
