Question

 A sample of 7.89 g of sodium is made to react with 68.4 g chlorine. Given the following information: a. All of the sodium sample reacted;

b. Some of the chlorine did not react; and

c. Sodium chloride is the only product

Is it possible to determine the mass of sodium chloride produced? Why or why not?

Answer 1

Yes it is possible

The balanced equation is,

$2Na(s)+Cl_2(g) → 2NaCl(s) .$

Moles of sodium $=\frac{7.89}{23}=0.34moles$

Mass of NaCl$=0.34× 58.44 =19.87grams$
