Calculate the number of moles of sodium chloride (NaCl) formed if 0.345
nalin [4]

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.
