Answer :
Answer:
4 grams of Sodium needs 6.165 grams of Chlorine
Explanation:
As per the equation, let us calculate the mole ratio.
Na+Cl---->NaCl
It can be observed from the balanced chemical equation that
1 mole of Na needs 1 mole of Cl
In term of mass, it can be stated that
23 grams of Sodium needs 35.45 grams of Chlorine
or,1 grams of Sodium needs (35.45/23) grams of Chlorine
so 4 grams of Sodium needs (35.45*4/23) grams of Chlorine
so 4 grams of Sodium needs 6.165 grams of Chlorine
The mass of chlorine required is 6 grams.
Given:
The 4 grams of sodium and 10 grams of sodium chloride (table salt).
To find:
The grams of chlorine to produce 10 grams of table salt
Solution:
[tex]Na+Cl\rightarrow NaCl[/tex]
Mass of sodium present = 4 g
Mass of chlorine needed = x
Mass of sodium chloride required to produce = 10 g
According to the law of conservation of mass:
Total mass of reactants = Total mass of products
[tex]Na+Cl\rightarrow NaCl[/tex]
Total mass of reactants = (4 +x)g
Total mass of products = 10 g
[tex](4 +x )g = 10 g\\\\x = 10 g - 4 g = 6 g[/tex]
The mass of chlorine required is 6 grams.
