Question

Calculate the number of moles of sodium chloride (NaCl) formed if 0.345

Answer 1

Answer : The number of moles of $NaCl$ formed are, 0.69 moles.

Explanation : Given,

Moles of $CaCl_2$ = 0.345 mol

Now we have to calculate the moles of $NaCl$

The balanced chemical equation is:

$1Na_2CO_2(aq)+1CaCl_2(aq)\rightarrow 1CaCO_3(s)+2NaCl(aq)$

From the balanced reaction, we conclude that

As, 1 mole of $CaCl_2$ react to give 2 moles of $NaCl$

So, 0.345 mole of $CaCl_2$ react to give $2\times 0.345=0.69$ mole of $NaCl$

Therefore, the number of moles of $NaCl$ formed are, 0.69 moles.
